When you punch it hard, it feels like a solid, but if you poke it slow it feels like a liquid. It pours, but you can also squeeze it. Oobleck has properties of both a solid AND a liquid! We can make oobleck act like both a solid and a liquid. A liquid like this is called a non-Newtonian fluid because it does not follow the rules that Newton discovered most liquids follow. Pretty cool, huh?
Here's the recipe for oobleck -- make some at home!
- 2 cups cornstarch
