Slime is non-Newtonian fluid, which means that it defies the laws of classical physics. How cool is that?! Slime starts with a polymer base, which in our case is glue. A “polymer” is a chemistry term for a substance that’s made of many little chains of molecules– “poly” means “many”, and “mer” means part in Greek. These chains easily slide past each other, which allows polymers to stretch and deform really easily. But when we add our activator, contact solution, it causes a chemical reaction that links some of these polymer chains together. These extra linkages between the chemical chains in the glue make the mixture stiffer. However, these cross-linkages break and deform easily, which is why slime feels more solid than glue, but is still super stretchy.Common activators for slime recipes are contact solution, powdered laundry detergent, and Borax. All of these contain boric acid which causes the chemical reaction! Fun fact: snails make their own slime to help them move, climb, and protect them from the sun!

It's so fun to get your hands dirty and play with squishy, slimy, ooze! Here's how my son and I made slime with cornstarch. Since my son's favorite is green, he decided neon green was the perfect shade for his cornstarch slime.Want more slimey science fun without the hassle of gathering materials?

We started by dumping a 1/4 cup of water into a turkey roasting pan. The tall sides of the roasting pan helped keep the water from flowing over the edges.

aa312ed974ba7.jpg

My enthusiastic little slime chef also added 1/2 cup of cornstarch.

a33de0d2a95d2.jpg

He added three drops of food coloring (a little goes a long way!) to get the slime to a satisfactory shade of neon green.

a9d6c298d5c06.jpg

Now we're getting to the good stuff! My son loved mixing his concoction with his hands (although you can stir the mixture with a spoon if you'd like). 

a87d7bb3556b9.jpg

Ooze is fun to play with on its own, but of course my son wanted to add a toy into the mix! He had lots of fun slithering his rubber snake around in the cornstarch slime--and the snake created lots of cool textures and patterns. All in all, a fantastic (if a bit messy!) activity that my son really loved. Oh, and here's a tip: If your slime starts to harden, just add a bit of water to make it fluid again.

Make Slime With Cornstarch

experiment

easy experiment

If you’ve ever wondered why it might be hard to get out of quicksand, it’s because it can act like both a liquid and a solid. Cornstarch slime is a fun substance that does this too! When a substance like this has properties of both liquids and solids, they are called non-Newtonian fluids, which you’ll learn more about in this experiment. You’ll also explore what interactions make it go from one state to another. When you slowly press your fingers into cornstarch slime —stored in a Ziploc bag —it’ll feel like a liquid. But when you quickly press your fingers into it, it becomes as hard as a rock! Why do you think that is?Want more slimey science fun without the hassle of gathering materials?

Pour two cups of cornstarch into the bag.

51d0beca5abb.jpeg

Add a few drops of food coloring to the water until you get a color you like.

aa0545539f5e.jpeg

Pour a cup of water into the bag (avoid filling the bag more than halfway) and mix with the cornstarch until it’s the consistency of runny cake batter. (If it’s too thick, add an additional tablespoon of water.)

d1dcbaef85ac.jpeg

With both hands, apply pressure quickly and feel how the cornstarch slime becomes firm and solid.

b335229f5db0.jpeg

Release it and feel the mixture become runny once again in the bag. Experiment with the speed at which pressure is applied. Poke it fast and poke it slow. You just made a non-Newtonian fluid!

We all know that certain substances change from solids to liquids to gases with temperature: water freezes to become ice or boils to become steam. But for non-Newtonian fluids, this change happens based on pressure instead of temperature. If you push down slowly with your fingers, the substance stays liquid, making a well around your fingers. If you push down quickly, it becomes firm beneath your fingers. If you had a life-size tub of cornstarch slime, how would you run across it? With fast stomps or slow steps?

magnets

Pull together a batch of&nbsp;magnetic slime! Polymers are really big molecules, made up of lots and lots of smaller molecules joined together. They can make materials bouncy like a rubber ball, stiff like a plastic toy, or stretchy like a piece of gum. One great way to play around with polymers -- and to do some hands-on experimentation with chemistry in general -- is to make your own slime. In this experiment, we uplevel your standard green goo to jet-black magnetic slime that will magically move and dance without you even touching it! Follow along below or in our <a href="https://www.youtube.com/watch?v=5BH7II5S9gk">How to Make Magnetic Slime</a>&nbsp;video tutorial!Want to learn more about chemistry without the hassle of gathering materials?

Add a tablespoon of iron oxide powder into your disposable cup or bowl. 

af5b038c797cd.jpg

Add 2 tablespoons of liquid starch. Use a craft  stick to mix the ingredients until the liquid is uniform and smooth.

a385d698666f3.jpg

Add 2 tablespoons of white glue and stir your mixture until you get an even consistency. You may need to scrape the mixture off your craft stick periodically to keep mixing.

aa0517fd9c0af.jpg

At this point, we put on our gloves as things start to get a little messy! Scoop out the black slime and knead it with your hands. It should start to dry as you do so. Keep kneading until your slime is smooth and dry. If needed, you can gently dab it on a paper towel to help with the drying process.

a3e5c41a3b7a4.jpg

Your slime should now be safe to handle without getting your hands black! Take your magnets and see how they interact with the slime.Try stretching out a long tendril of slime. Place the magnets near the slime and watch as the slime slowly creeps over to be closer to the magnet.

ae4178a6bcaca.jpg

For some extra experimentation, try varying your ratio of iron oxide to glue to liquid starch and observe the results. Depending on your ratio, the slime can either be very thick or thin and it will interact differently with the magnets. What combination worked the best for you?

My kids love anything colorful and messy, so I'm always on the lookout for gooey projects! We've explored slime before, so I knew we also had to check out these glow-in-the-dark bouncy balls. My kids were thrilled to find out we could make our own and bounce them in the dark! Borax (sodium tetraborate) is a naturally-occurring mineral salt commonly used as a laundry booster or cleaner. As with any other cleaning product, it should be kept away from children not under direct supervision of an adult. Do not allow children to ingest Borax. If consumed, contact a poison control center immediately.Want to learn more about chemistry without the hassle of gathering materials?

Mix 1/2 tablespoon of borax with 1 1/2 cups of warm water. Stir your borax solution with a craft stick until most of the powder has dissolved.

afba9ad96944d.jpg

In another cup, mix 1 tablespoon of glue, 1 tablespoon of cornstarch, and 1 teaspoon of fluorescent paint. Stir well with a new craft stick.

ace9ddb0710c8.jpg

Add 2 tablespoons of your borax solution to your cornstarch and glue mixture. Stir the mixture with a craft stick for about a minute. As you stir, you'll see a sticky, slimy material start to form around your craft stick!

aec66304ed8bb.jpg

Time to get messy! Pull the slime off of your craft stick and knead it with your hands. If your slime is really sticky, dip it into your borax solution and it'll get smoother. Once you've worked your slime in your hands for a few minutes, it should start to dry and harden. Roll your slime up into a ball and try bouncing it on the ground!  If your slime isn't bouncy enough, try using less cornstarch or more glue. Keep experimenting for the perfect recipe! 

a5e954b0cf504.jpg

To get more color, try making several slime balls with different colors of paint. Tear off parts of each ball and mix them together. To make swirling patterns of color, squeeze, and stretch the slime!

Shine a blacklight on your slime balls to make them glow. What's going on? This project uses a "black light" to make a glowing bouncy ball. Black lights look a little bit purple, but it's the light they produce that you can't see that's really interesting. Black lights produce ultraviolet (UV) light. Our eyes can't perceive UV light, but our skin can feel it; UV light is the reason we get sunburns. Some substances, like fluorescent paint, will glow under UV light. The paint absorbs the energy in the UV light, and then emits it as visible light. Groovy!

Keep in mind your slime balls will keep hardening as they dry out. You can store them in an airtight bag to save them.
