Experiment 12 , a chain game that consists of 12 chapters each created by 12 different indie developers, is available now for Windows PC.

Contributing developers include Ian Snyder, Jack King-Spooner, Zaratustra, Richard Perrin, Michael Brough, Robert Yang, Alan Hazelden, TheBlackMask, Jasper Byrne, Jake Clover and Benn Powell. Each chapter features contrasting artstyles and genres.

Super Hexagon and VVVVVV creator Terry Cavanagh — who posted a Vine clip last April featuring several cancelled projects, such as a dance-based role-playing game and a first-person shooter — is also involved. Cavanagh is currently working on a new puzzle game tentatively called Halting Problem.

The game is available to download and play for free on Windows PC .

12 creepy mini-games in one package

Experiment 12 is a package of 12 free indie horror games, each level designed by a different programmer.

Twelve games from different minds

Experiment 12 brings twelve stylistically different games to your PC in one package. While the content of each level is different, all the games have a creepy atmosphere: navigate mazes, avoid missiles and dodge enemies; solve puzzles and explore 3D environments similar to Slender , on an island, with a flashlight, at night, and in the rain.

Experiment 12 is a collaboration between independent programmers Terry Cavanagh, Ian Snyder, Jack King-Spooner, Zarathustra, Richard Perrin, Michael Brough, Robert Yang, Alan Hazelden, TheBlackMask, Jasper Byrne, Jake Clover, and Benn Powell.

Navigation is tricky

Navigation in all games in Experiment 12 is done using the keyboard. Learning the ins and outs is one of the challenging parts of the game.

Mix of different styles

The graphics used in the different levels of Experiment 12 are pretty varied, from 80's style roughly drawn characters in retro 2D to high-quality 3D graphics.

Colorful mix, but the content is lacking

Experiment 12 is a colorful collection of mini-games. The mix of styles is stimulating, but it lacks a coherent story. The overall result is less than challenging.

  • 12 different scary games
  • Different styles of play
  • Good sound effects
  • Little cohesion between games
  • No single action
  • Barely challenging

...What a ride! From what I was able to understand in this game (which was barely anything), it was an amazing story.

Hmm... Although, in Robert Yang's stage, there were characters showing up as Chinese stamps; is that supposed to happen?

I love the idea of just having a guideline then having 12 artists interpret it and then make a story out of it. It's really confusing; I don't know if I'm even making sense. XD

Reply

Oh and also...I love how you don't really have a strict set of rules; you can play however you want, and pretty much get the same story.

@aznwulf96: I had the same issue with the Chinese stamps. I assumed it was part of the cryptic nature of the chapter, but now that you mention it, I noticed the screenshot on the menu looks like it has english text there. I think the stamps do correspond 1-to-1 with letters. Even on my first playthrough, I interpreted the final screen (a string of 3-2-7) as "end of chapter," and if you look carefully, the symbols for where the Es are match. So with some tedious homework, it looks like there is a cryptogram to be solved throughout the level, but it could also just be a bug in the system somewhere. I think it works well for the game though.

experiment 12

A file in the package came up positive in Avast virus check.

Think I missed something with this one - tried chapters 1 & 2, both came across as a complete mess. Gameplay awful, "enemies" pointless, goals unclear, left wondering what the point was. Skipped to the last chapter, gameplay a little better, still left wondering what the point was. I like retro-styled games, I like platformers, I like puzzlers; I really don't like this though, sorry!

Wot I Think: Experiment 12

The (Indie) Stars Align

Terry Cavanagh. Jasper Byrne. Ian Snyder. Jack King-Spooner. Richard Perrin. Zaratustra. Michael Brough. Robert Yang. Alan Hazelden. Benn Powell. Jake Clover. TheBlackMask.

You have probably played games by all of these people. VVVVVV might ring a bell. Maybe Lone Survivor or Kairo . Or, if you're really, really cool, Blues For Mittavinda . Etc, etc, etc. You get the idea. But now they've all congealed into a hivemind and made one giant, multi-stage/setting/genre melting pot of madness. Each developer had three days to make a contribution, and then the next creator picked up where the previous left off. Experiment 12 is insane. Experiment 12 is inconsistent. Experiment 12 is beautiful.

There are many madnesses. Cavanagh turns you into a weeping sack of malfunctioning organs, while King-Spooner, Snyder, Zaratustra, and Byrne put various decaying mental states under the magnifying glass - often through wildly distorted platforming mechanics. Sometimes you play as mentally decaying test subjects directly, platforming, adventuring, puzzle-solving, or blasting through everything from pixelated retroscapes to desolately dreary 3D islands. Other times, you're only observing them, dispassionately gazing through a screen within your own screen - acting as though that really makes any difference.

experiment 12

In most of Experiment 12's chapters, challenge isn't really an issue. You can die, but only a couple games halt progress full-stop. Most opt to treat in-game life as a fate far worse than death, greeting failure with imagery of flesh and bone sloughing and snapping, helpless bodies crying out in anguish. And oh, the sounds that accompany these sights. Menacing rumbles, vein-rattling drones, divorced and disinterested keyboards typing away. Experiment 12 is all at once unsettlingly intimate with the human body and coldly clinical - like a doctor whose icy stethoscope singes your skin. I felt like it was constantly pushing my buttons just to see how I'd react.

Of those early, more overtly insane scenarios, I found Snyder's especially interesting. It deals with many of the aforementioned themes while inhabiting a wildly abstract cube-based puzzler... that occasionally bursts into violently colorful 3D hallucinations. Stray too far from your cuboid prison's walls and the entire thing begins convulsing into an amorphous, infinitely shifting mass. All the while, stark white letters pop up on an abyssal black background, the terrified ramblings of a failing mind.

It's unabashedly obtuse, sure, but it's that rare instance of a game where mechanics and feeling meet perfectly in the middle. I was losing control of my mind, and even simple tasks like movement took every ounce of my concentration. I needed something solid to grab ahold of, anything to keep me from unraveling.

experiment 12

Michael Brough's physical and mental exploration of multiple personalities is a similarly coherent treat, with devious puzzles growing ever more complex each time a new, er, you joins the fray. Before long, you end up maneuvering a small army of individual bodies with a single input, each simultaneously working together and against each other in separate rooms - all in a confused attempt to solve singular, overarching puzzles. Naturally, your character's dialogue breaks down more and more as time goes on. It really is brilliant - in an overwhelming, highly unsettling sort of way.

Later chapters delve into the equally ugly recesses of other elements of this nightmarish testing initiative. For example, its talking head leaders in the case of Perrin's voyeuristic first-person adventure, a reporter who may or may not exist in the same continuity as everything else in TheBlackMask's bit, and even an AI monitoring the whole operation in Hazelden's ASCII labyrinth. The conspiracy is everywhere. Nothing is safe. Or maybe I'm just imagining all of it. Insanity really is the darndest thing.

Or at least, that's how I read it. Really, a big part of Experiment 12's appeal for me was attempting to pluck out key strands of DNA that bound the wildly disparate production together. Sometimes I relied on exceedingly clever mechanical and thematic callbacks to previous chapters, but other elements struck me as only loosely connected (which makes sense, given the way they were developed), and the rest of the "story" was, well, all in my head. But my interpretation - of story, of intention, of meaning - quickly took on a life of its own. I desperately wanted to make sense of the madness, even if it meant cracking my brain in half in the process. Come to think of it, maybe that's its own sort of madness.

experiment 12

That said, a few of Experiment 12's chapters aren't "fun" in a traditional sense, and I can't help but wonder if some of its brain-sizzling bizarro moments came from a desire to be weird for weirdness' sake. Couple that with the inherent lack of length such quick vignettes conjure, and you're left with a couple bits that feel less substantial and more like pure shock value. Some slices, meanwhile, are far weaker than others - with Yang and Powell's especially failing to really gel with the theme and, in the case of the former, make much sense at all.

Despite that, however, the behemoth collaborative effort succeeds gloriously as a whole that gives you just enough to go on while simultaneously leaving so much space that your own battered mind can't help but wander the gaps, pacing back-and-forth and muttering mad theories to no one in particular. It's a truly fascinating thing.

Experiment 12 is so all-over-the-place that it's very nearly impossible to discuss in a coherent fashion. It leapfrogs between genres like an escaped lab mutant barreling through traffic. It means nothing, it means a million tiny things to each of its creators, it means whatever you think it means. To be honest, I've gone back and forth between appreciating it and thinking it's too full of itself for its own good, like, 20 times just during the process of writing this article. But I'm pretty sure I like it. Quite a bit, even. I can't really think of another game collection that's so consistently left me straddling a line somewhere between obsessive curiosity and lurching nausea. In a good way.

experiment 12

I never felt comfortable while playing Experiment 12. That's probably both the best and worst thing I can say about it. The only truly consistent thing about my experience with it, I think, was the creeping sense of unease that emerged from subject matter, stifling atmosphere, and schizoid shifts in game mechanics. It's got its fair share of issues in all of those areas, but the scope and diversity of this collection's vision is immense, and some of the denser details will surprise you. And come on: it's free. To skip this one would be an act of utter, well, madness.

Sat / act prep online guides and tips, 37 cool science experiments for kids to do at home.

author image

General Education

feature_scienceexperiment

Are you looking for cool science experiments for kids at home or for class? We've got you covered! We've compiled a list of 37 of the best science experiments for kids that cover areas of science ranging from outer space to dinosaurs to chemical reactions. By doing these easy science experiments, kids will make their own blubber and see how polar bears stay warm, make a rain cloud in a jar to observe how weather changes, create a potato battery that'll really power a lightbulb, and more.

Below are 37 of the best science projects for kids to try. For each one we include a description of the experiment, which area(s) of science it teaches kids about, how difficult it is (easy/medium/hard), how messy it is (low/medium/high), and the materials you need to do the project. Note that experiments labelled "hard" are definitely still doable; they just require more materials or time than most of these other science experiments for kids.

#1: Insect Hotels

  • Teaches Kids About: Zoology
  • Difficulty Level: Medium
  • Messiness Level: Medium

Insect hotels can be as simple (just a few sticks wrapped in a bundle) or as elaborate as you'd like, and they're a great way for kids to get creative making the hotel and then get rewarded by seeing who has moved into the home they built. After creating a hotel with hiding places for bugs, place it outside (near a garden is often a good spot), wait a few days, then check it to see who has occupied the "rooms." You can also use a bug ID book or app to try and identify the visitors.

  • Materials Needed
  • Shadow box or other box with multiple compartments
  • Hot glue gun with glue
  • Sticks, bark, small rocks, dried leaves, bits of yarn/wool, etc.

insect hotel

#2: DIY Lava Lamp

  • Teaches Kids About: Chemical reactions
  • Difficulty Level: Easy

In this quick and fun science experiment, kids will mix water, oil, food coloring, and antacid tablets to create their own (temporary) lava lamp . Oil and water don't mix easily, and the antacid tablets will cause the oil to form little globules that are dyed by the food coloring. Just add the ingredients together and you'll end up with a homemade lava lamp!

  • Vegetable oil
  • Food coloring
  • Antacid tablets

#3: Magnetic Slime

  • Teaches Kids About: Magnets
  • Messiness Level: High (The slime is black and will slightly dye your fingers when you play with it, but it washes off easily.)

A step up from silly putty and Play-Doh, magnetic slime is fun to play with but also teaches kids about magnets and how they attract and repel each other. Some of the ingredients you aren't likely to have around the house, but they can all be purchased online. After mixing the ingredients together, you can use the neodymium magnet (regular magnets won't be strong enough) to make the magnetic slime move without touching it!

  • Liquid starch
  • Adhesive glue
  • Iron oxide powder
  • Neodymium (rare earth) magnet

#4: Baking Soda Volcanoes

  • Teaches Kids About: Chemical reactions, earth science
  • Difficulty Level: Easy-medium
  • Messiness Level: High

Baking soda volcanoes are one of the classic science projects for kids, and they're also one of the most popular. It's hard to top the excitement of a volcano erupting inside your home. This experiment can also be as simple or in-depth as you like. For the eruption, all you need is baking soda and vinegar (dishwashing detergent adds some extra power to the eruption), but you can make the "volcano" as elaborate and lifelike as you wish.

  • Baking soda
  • Dishwashing detergent
  • Large mason jar or soda bottle
  • Playdough or aluminum foil to make the "volcano"
  • Additional items to place around the volcano (optional)
  • Food coloring (optional)

#5: Tornado in a Jar

  • Teaches Kids About: Weather
  • Messiness Level: Low

This is one of the quick and easy and science experiments for kids to teach them about weather. It only takes about five minutes and a few materials to set up, but once you have it ready you and your kids can create your own miniature tornado whose vortex you can see and the strength of which you can change depending on how quickly you swirl the jar.

  • Glitter (optional)

#6: Colored Celery Experiment

  • Teaches Kids About: Plants

This celery science experiment is another classic science experiment that parents and teachers like because it's easy to do and gives kids a great visual understanding of how transpiration works and how plants get water and nutrients. Just place celery stalks in cups of colored water, wait at least a day, and you'll see the celery leaves take on the color of the water. This happens because celery stalks (like other plants) contain small capillaries that they use to transport water and nutrients throughout the plant.

  • Celery stalks (can also use white flowers or pale-colored cabbage)

#7: Rain Cloud in a Jar

This experiment teaches kids about weather and lets them learn how clouds form by making their own rain cloud . This is definitely a science project that requires adult supervision since it uses boiling water as one of the ingredients, but once you pour the water into a glass jar, the experiment is fast and easy, and you'll be rewarded with a little cloud forming in the jar due to condensation.

  • Glass jar with a lid
  • Boiling water
  • Aerosol hairspray

body_rockcandy

#8: Edible Rock Candy

  • Teaches Kids About: Crystal formation

It takes about a week for the crystals of this rock candy experiment to form, but once they have you'll be able to eat the results! After creating a sugar solution, you'll fill jars with it and dangle strings in them that'll slowly become covered with the crystals. This experiment involves heating and pouring boiling water, so adult supervision is necessary, once that step is complete, even very young kids will be excited to watch crystals slowly form.

  • Large saucepan
  • Clothespins
  • String or small skewers
  • Candy flavoring (optional)

#9: Water Xylophone

  • Teaches Kids About: Sound waves

With just some basic materials you can create your own musical instrument to teach kids about sound waves. In this water xylophone experiment , you'll fill glass jars with varying levels of water. Once they're all lined up, kids can hit the sides with wooden sticks and see how the itch differs depending on how much water is in the jar (more water=lower pitch, less water=higher pitch). This is because sound waves travel differently depending on how full the jars are with water.

  • Wooden sticks/skewers

#10: Blood Model in a Jar

  • Teaches Kids About: Human biology

This blood model experiment is a great way to get kids to visual what their blood looks like and how complicated it really is. Each ingredient represents a different component of blood (plasma, platelets, red blood cells, etc.), so you just add a certain amount of each to the jar, swirl it around a bit, and you have a model of what your blood looks like.

  • Empty jar or bottle
  • Red cinnamon candies
  • Marshmallows or dry white lima beans
  • White sprinkles

#11: Potato Battery

  • Teaches Kids About: Electricity
  • Difficulty Level: Hard

Did you know that a simple potato can produce enough energy to keep a light bulb lit for over a month? You can create a simple potato battery to show kids. There are kits that provide all the necessary materials and how to set it up, but if you don't purchase one of these it can be a bit trickier to gather everything you need and assemble it correctly. Once it's set though, you'll have your own farm grown battery!

  • Fresh potato
  • Galvanized nail
  • Copper coin

body_pulley

#12: Homemade Pulley

  • Teaches Kids About: Simple machines

This science activity requires some materials you may not already have, but once you've gotten them, the homemade pulley takes only a few minutes to set up, and you can leave the pulley up for your kids to play with all year round. This pulley is best set up outside, but can also be done indoors.

  • Clothesline
  • 2 clothesline pulleys

#13: Light Refraction

  • Teaches Kids About: Light

This light refraction experiment takes only a few minutes to set up and uses basic materials, but it's a great way to show kids how light travels. You'll draw two arrows on a sticky note, stick it to the wall, then fill a clear water bottle with water. As you move the water bottle in front of the arrows, the arrows will appear to change the direction they're pointing. This is because of the refraction that occurs when light passes through materials like water and plastic.

  • Sticky note
  • Transparent water bottle

#14: Nature Journaling

  • Teaches Kids About: Ecology, scientific observation

A nature journal is a great way to encourage kids to be creative and really pay attention to what's going on around them. All you need is a blank journal (you can buy one or make your own) along with something to write with. Then just go outside and encourage your children to write or draw what they notice. This could include descriptions of animals they see, tracings of leaves, a drawing of a beautiful flower, etc. Encourage your kids to ask questions about what they observe (Why do birds need to build nests? Why is this flower so brightly colored?) and explain to them that scientists collect research by doing exactly what they're doing now.

  • Blank journal or notebook
  • Pens/pencils/crayons/markers
  • Tape or glue for adding items to the journal

#15: DIY Solar Oven

  • Teaches Kids About: Solar energy

This homemade solar oven definitely requires some adult help to set up, but after it's ready you'll have your own mini oven that uses energy from the sun to make s'mores or melt cheese on pizza. While the food is cooking, you can explain to kids how the oven uses the sun's rays to heat the food.

  • Aluminum foil
  • Knife or box cutter
  • Permanent marker
  • Plastic cling wrap
  • Black construction paper

body_polarbears-1

#16: Animal Blubber Simulation

  • Teaches Kids About: Ecology, zoology

If your kids are curious about how animals like polar bears and seals stay warm in polar climates, you can go beyond just explaining it to them; you can actually have them make some of their own blubber and test it out. After you've filled up a large bowl with ice water and let it sit for a few minutes to get really cold, have your kids dip a bare hand in and see how many seconds they can last before their hand gets too cold. Next, coat one of their fingers in shortening and repeat the experiment. Your child will notice that, with the shortening acting like a protective layer of blubber, they don't feel the cold water nearly as much.

  • Bowl of ice water

#17: Static Electricity Butterfly

This experiment is a great way for young kids to learn about static electricity, and it's more fun and visual than just having them rub balloons against their heads. First you'll create a butterfly, using thick paper (such as cardstock) for the body and tissue paper for the wings. Then, blow up the balloon, have the kids rub it against their head for a few seconds, then move the balloon to just above the butterfly's wings. The wings will move towards the balloon due to static electricity, and it'll look like the butterfly is flying.

  • Tissue paper
  • Thick paper
  • Glue stick/glue

#18: Edible Double Helix

  • Teaches Kids About: Genetics

If your kids are learning about genetics, you can do this edible double helix craft to show them how DNA is formed, what its different parts are, and what it looks like. The licorice will form the sides or backbone of the DNA and each color of marshmallow will represent one of the four chemical bases. Kids will be able to see that only certain chemical bases pair with each other.

  • 2 pieces of licorice
  • 12 toothpicks
  • Small marshmallows in 4 colors (9 of each color)
  • 5 paperclips

#19: Leak-Proof Bag

  • Teaches Kids About: Molecules, plastics

This is an easy experiment that'll appeal to kids of a variety of ages. Just take a zip-lock bag, fill it about ⅔ of the way with water, and close the top. Next, poke a few sharp objects (like bamboo skewers or sharp pencils) through one end and out the other. At this point you may want to dangle the bag above your child's head, but no need to worry about spills because the bag won't leak? Why not? It's because the plastic used to make zip-lock bags is made of polymers, or long chains of molecules that'll quickly join back together when they're forced apart.

  • Zip-lock bags
  • Objects with sharp ends (pencils, bamboo skewers, etc.)

body_leaves

#20: How Do Leaves Breathe?

  • Teaches Kids About: Plant science

It takes a few hours to see the results of this leaf experiment , but it couldn't be easier to set up, and kids will love to see a leaf actually "breathing." Just get a large-ish leaf, place it in a bowl (glass works best so you can see everything) filled with water, place a small rock on the leaf to weigh it down, and leave it somewhere sunny. Come back in a few hours and you'll see little bubbles in the water created when the leaf releases the oxygen it created during photosynthesis.

  • Large bowl (preferably glass)
  • Magnifying glass (optional)

#21: Popsicle Stick Catapults

Kids will love shooting pom poms out of these homemade popsicle stick catapults . After assembling the catapults out of popsicle sticks, rubber bands, and plastic spoons, they're ready to launch pom poms or other lightweight objects. To teach kids about simple machines, you can ask them about how they think the catapults work, what they should do to make the pom poms go a farther/shorter distance, and how the catapult could be made more powerful.

  • Popsicle sticks
  • Rubber bands
  • Plastic spoons
  • Paint (optional)

#22: Elephant Toothpaste

You won't want to do this experiment near anything that's difficult to clean (outside may be best), but kids will love seeing this " elephant toothpaste " crazily overflowing the bottle and oozing everywhere. Pour the hydrogen peroxide, food coloring, and dishwashing soap into the bottle, and in the cup mix the yeast packet with some warm water for about 30 seconds. Then, add the yeast mixture to the bottle, stand back, and watch the solution become a massive foamy mixture that pours out of the bottle! The "toothpaste" is formed when the yeast removed the oxygen bubbles from the hydrogen peroxide which created foam. This is an exothermic reaction, and it creates heat as well as foam (you can have kids notice that the bottle became warm as the reaction occurred).

  • Clean 16-oz soda bottle
  • 6% solution of hydrogen peroxide
  • 1 packet of dry yeast
  • Dishwashing soap

#23: How Do Penguins Stay Dry?

Penguins, and many other birds, have special oil-producing glands that coat their feathers with a protective layer that causes water to slide right off them, keeping them warm and dry. You can demonstrate this to kids with this penguin craft by having them color a picture of a penguin with crayons, then spraying the picture with water. The wax from the crayons will have created a protective layer like the oil actual birds coat themselves with, and the paper won't absorb the water.

  • Penguin image (included in link)
  • Spray bottle
  • Blue food coloring (optional)

body_erosion

#24: Rock Weathering Experiment

  • Teaches Kids About: Geology

This mechanical weathering experiment teaches kids why and how rocks break down or erode. Take two pieces of clay, form them into balls, and wrap them in plastic wrap. Then, leave one out while placing the other in the freezer overnight. The next day, unwrap and compare them. You can repeat freezing the one piece of clay every night for several days to see how much more cracked and weathered it gets than the piece of clay that wasn't frozen. It may even begin to crumble. This weathering also happens to rocks when they are subjected to extreme temperatures, and it's one of the causes of erosion.

  • Plastic wrap

#25: Saltwater Density

  • Teaches Kids About: Water density

For this saltwater density experiment , you'll fill four clear glasses with water, then add salt to one glass, sugar to one glass, and baking soda to one glass, leaving one glass with just water. Then, float small plastic pieces or grapes in each of the glasses and observe whether they float or not. Saltwater is denser than freshwater, which means some objects may float in saltwater that would sink in freshwater. You can use this experiment to teach kids about the ocean and other bodies of saltwater, such as the Dead Sea, which is so salty people can easily float on top of it.

  • Four clear glasses
  • Lightweight plastic objects or small grapes

#26: Starburst Rock Cycle

With just a package of Starbursts and a few other materials, you can create models of each of the three rock types: igneous, sedimentary, and metamorphic. Sedimentary "rocks" will be created by pressing thin layers of Starbursts together, metamorphic by heating and pressing Starbursts, and igneous by applying high levels of heat to the Starbursts. Kids will learn how different types of rocks are forms and how the three rock types look different from each other.

  • Toaster oven

#27: Inertia Wagon Experiment

  • Teaches Kids About: Inertia

This simple experiment teaches kids about inertia (as well as the importance of seatbelts!). Take a small wagon, fill it with a tall stack of books, then have one of your children pull it around then stop abruptly. They won't be able to suddenly stop the wagon without the stack of books falling. You can have the kids predict which direction they think the books will fall and explain that this happens because of inertia, or Newton's first law.

  • Stack of books

#28: Dinosaur Tracks

  • Teaches Kids About: Paleontology

How are some dinosaur tracks still visible millions of years later? By mixing together several ingredients, you'll get a claylike mixture you can press your hands/feet or dinosaur models into to make dinosaur track imprints . The mixture will harden and the imprints will remain, showing kids how dinosaur (and early human) tracks can stay in rock for such a long period of time.

  • Used coffee grounds
  • Wooden spoon
  • Rolling pin

#29: Sidewalk Constellations

  • Teaches Kids About: Astronomy

If you do this sidewalk constellation craft , you'll be able to see the Big Dipper and Orion's Belt in the daylight. On the sidewalk, have kids draw the lines of constellations (using constellation diagrams for guidance) and place stones where the stars are. You can then look at astronomy charts to see where the constellations they drew will be in the sky.

  • Sidewalk chalk
  • Small stones
  • Diagrams of constellations

#30: Lung Model

By building a lung model , you can teach kids about respiration and how their lungs work. After cutting off the bottom of a plastic bottle, you'll stretch a balloon around the opened end and insert another balloon through the mouth of the bottle. You'll then push a straw through the neck of the bottle and secure it with a rubber band and play dough. By blowing into the straw, the balloons will inflate then deflate, similar to how our lungs work.

  • Plastic bottle
  • Rubber band

body_dinosaurbones

#31: Homemade Dinosaur Bones

By mixing just flour, salt, and water, you'll create a basic salt dough that'll harden when baked. You can use this dough to make homemade dinosaur bones and teach kids about paleontology. You can use books or diagrams to learn how different dinosaur bones were shaped, and you can even bury the bones in a sandpit or something similar and then excavate them the way real paleontologists do.

  • Images of dinosaur bones

#32: Clay and Toothpick Molecules

There are many variations on homemade molecule science crafts . This one uses clay and toothpicks, although gumdrops or even small pieces of fruit like grapes can be used in place of clay. Roll the clay into balls and use molecule diagrams to attach the clay to toothpicks in the shape of the molecules. Kids can make numerous types of molecules and learn how atoms bond together to form molecules.

  • Clay or gumdrops (in four colors)
  • Diagrams of molecules

#33: Articulated Hand Model

By creating an articulated hand model , you can teach kids about bones, joints, and how our hands are able to move in many ways and accomplish so many different tasks. After creating a hand out of thin foam, kids will cut straws to represent the different bones in the hand and glue them to the fingers of the hand models. You'll then thread yarn (which represents tendons) through the straws, stabilize the model with a chopstick or other small stick, and end up with a hand model that moves and bends the way actual human hands do.

  • Straws (paper work best)
  • Twine or yarn

#34: Solar Energy Experiment

  • Teaches Kids About: Solar energy, light rays

This solar energy science experiment will teach kids about solar energy and how different colors absorb different amounts of energy. In a sunny spot outside, place six colored pieces of paper next to each other, and place an ice cube in the middle of each paper. Then, observe how quickly each of the ice cubes melt. The ice cube on the black piece of paper will melt fastest since black absorbs the most light (all the light ray colors), while the ice cube on the white paper will melt slowest since white absorbs the least light (it instead reflects light). You can then explain why certain colors look the way they do. (Colors besides black and white absorb all light except for the one ray color they reflect; this is the color they appear to us.)

  • 6 squares of differently colored paper/cardstock (must include black paper and white paper)

#35: How to Make Lightning

  • Teaches Kids About: Electricity, weather

You don't need a storm to see lightning; you can actually create your own lightning at home . For younger kids this experiment requires adult help and supervision. You'll stick a thumbtack through the bottom of an aluminum tray, then stick the pencil eraser to the pushpin. You'll then rub the piece of wool over the aluminum tray, and then set the tray on the Styrofoam, where it'll create a small spark/tiny bolt of lightning!

  • Pencil with eraser
  • Aluminum tray or pie tin
  • Styrofoam tray

#36: Tie-Dyed Milk

  • Teaches Kids About: Surface tension

For this magic milk experiment , partly fill a shallow dish with milk, then add a one drop of each food coloring color to different parts of the milk. The food coloring will mostly stay where you placed it. Next, carefully add one drop of dish soap to the middle of the milk. It'll cause the food coloring to stream through the milk and away from the dish soap. This is because the dish soap breaks up the surface tension of the milk by dissolving the milk's fat molecules.

  • Shallow dish
  • Milk (high-fat works best)

body_stalactite

#37: How Do Stalactites Form?

Have you ever gone into a cave and seen huge stalactites hanging from the top of the cave? Stalactites are formed by dripping water. The water is filled with particles which slowly accumulate and harden over the years, forming stalactites. You can recreate that process with this stalactite experiment . By mixing a baking soda solution, dipping a piece of wool yarn in the jar and running it to another jar, you'll be able to observe baking soda particles forming and hardening along the yarn, similar to how stalactites grow.

  • Safety pins
  • 2 glass jars

Summary: Cool Science Experiments for Kids

Cache County fast-tracks a luxury ski resort’s shift toward exclusive oasis for the rich

Powder mountain, fueled by a major investment from the co-founder of netflix, is transforming into a destination for the elite..

(Rick Egan | The Salt Lake Tribune) The Sundown ski lift at Powder Mountain Ski Resort on Friday, December 8, 2023. Cache County Council members voted to let the resort build two new ski lifts ahead of the upcoming season.

A Utah ski area expanding its terrain for a wealthy customer base will get to buck Cache County zoning requirements to make good on its promise to install new lifts for next winter as it shifts from a family-run hub for winter sports to a partially private resort geared toward affluent skiers.

The Cache County Council voted 4–3 on Tuesday to allow Powder Mountain to bypass the usual zoning rules during the construction of its new Lighting Ridge and Raintree lifts — one of which will be private. This will enable the lifts to be installed in time for the 2024-25 season — a timeline deemed “critical” by the resort’s chief development officer, Brooke Hontz.

“What we are trying to do,” Hontz said, “is isolate this season.”

The decision follows Netflix co-founder Reed Hastings’ recent acquisition of a controlling stake in the resort, with goals to turn it into a luxury private and public skiing destination. Beginning this winter, Hastings plans to restrict access to more than 2,000 acres of previously public skiing terrain, making it available only to private members with membership fees ranging from $30,000 to $100,000.

The private terrain will be accessed via the previously public Mary’s and Village lifts, as well as a new Raintree lift. Raintree, which connects to newly acquired territory , is one of the four new lifts Powder Mountain wants to build this summer. All are part of $100 million in new investments Hastings pledged in September, shortly after investing in Powder Mountain.

The other three are public lifts. Only Raintree and Lightning Ridge are not included in the resort’s master plan, so Powder Mountain needed permission to start construction early. The council’s vote on Tuesday was an unusual step because it allows the resort to start building lifts before the full master plan is ready.

Adult passes for the next season are priced at $1,649, making the resort one of the most expensive in the state.

Hontz said the quality of the resort’s ski lifts justifies the steep prices.

“The experience you have,” she said, “is far greater than any dollar amount that we could put with that.”

With the acquisition of the Davenport area in March, Powder Mountain became the largest ski area in North America with about 12,000 total acres.

While most of the resort is in Weber County, the two new lifts approved Tuesday will be constructed in Cache County. The three dissenting council members expressed concerns about entering a development agreement, fearing the county might not be fully compensated for commercial skiing within its bounds.

Council member Nolan Gunnell requested the council review the agreement over the next couple of weeks before making a decision, but Hontz cautioned that even a two-week delay could disrupt the construction schedule and lead to environmental issues.

“Pardon my hesitancy to open the doors and say, ‘We’ve got to go ahead because of development and weather,’” Gunnell said. “But at the same time, we’ve got to sit here and say what’s best for the county.”

Council members Barbara Tidwell and David Erickson agreed, but others felt ready to move forward.

Hontz said she will be presenting the resort’s full master plan in the coming months.

COMMENTS

  1. Experiment 12-B

    This is a flying mount. Requires level 1 to 70 [ ( 70 )] Requires Apprentice Riding. "Some believe Experiment 12-B is the result of a covert SI-7 initiative, others consider it the outcome of embyronic tinkering by goblin scientists. No matter the case, this much is certain: given its strength, speed and agility, Experiment 12-B was a success!"

  4. Experiment 12

    Experiment 12 brings twelve stylistically different games to your PC in one package. While the content of each level is different, all the games have a creepy atmosphere: navigate mazes, avoid missiles and dodge enemies; solve puzzles and explore 3D environments similar to Slender , on an island, with a flashlight, at night, and in the rain.

  7. Experiment 12

    Experiment 12 combines a mix of puzzle and platform levels made in Flash, HTML5, Game Maker, and Unity, each built in a period of three days. In most levels, you can move around using [WASD] or the [arrow] keys and deploy an occasional action with [space], though one level does require mouse input.

  8. Experiment 12 (2013)

    Experiment 12 is a sci-fi/horror game that is, as the title suggests, experimental. The game is a work of collaborative fiction in 12 chapters, each made by a different indie developer over a period of 72 hours. Though each chapter varies widely in art style and gameplay, they unify to tell a story about human experimentation and illnesses both physical and mental.

  9. Wot I Think: Experiment 12

    Experiment 12 is inconsistent. Experiment 12 is beautiful. There are many madnesses. Cavanagh turns you into a weeping sack of malfunctioning organs, while King-Spooner, Snyder, Zaratustra, and Byrne put various decaying mental states under the magnifying glass - often through wildly distorted platforming mechanics.

  10. Experiment 12

    All prisoner's are encouraged to participate in prison experiments. Successful completion of any experiment will grant you early release from your stay here. Unfortunately, unsuccessful completion is usually the result of death. For this reason, we will thank you in advance. Good luck!
