It’s called oobleck: a non-Newtonian fluid that you can make at home. It acts like a liquid when poured, but apply a little bit of force to it, and it’ll turn into a solid substance:
To make your own oobleck you’ll need one cup of water, two cups of corn starch, and some food coloring. Mix it up in a bowl and that’s it. You can play with it like putty, or find a subwoofer and make it dance! Be careful though: oobleck can be messy!
Bonus fact: you can even walk on “water!”
