Squishy Science
The three states of matter are solid, liquid, and gas. But what about the squishy stuff? Learn more with these smooshy activities!
Oobleck

When is a liquid not always a liquid and a solid not always a solid? When it’s "Oobleck"! Explore Non-Newtonian fluids - solutions that change their state of matter under pressure! It’s easy to make and super fun to play with.
Square Bubbles

Most bubble wands are circular, so is that why bubbles come out round? What happens if you use a differently shaped bubble wand? Can you make a square bubble?
Bouncing Egg

We all know what happens when you drop a regular egg on the ground. When you add vinegar (and some patience), however, you end up with a bouncy, squishy object that changes everything you think you know about eggs!
Smooshy Slime

Who doesn’t love slime? Another example of a non-Newtonian fluid, slime is oobleck’s ooey-gooey cousin. When all of the ingredients in this activity are combined you get a squishy substance that is fun to stretch, shape, and smoosh.
