Ahmad's Science Club: Making Oobleck
There are 4 main states of matter: Solid, Liquid, Gas, and Plasma.
Oobleck is what is called a Non-Newtonian fluid. This means it holds 2 states at once.
Basically, it is both a solid and a liquid at the same time.
You can make your own!
Mix 2 cups of cornstarch with 1 cup of water in a bowl.
MIX THOROUGHLY and really get messy!
You'll feel it be quite firm. At this point you can poke it, punch it, pick it up and roll it around in a ball.
As long as there is a force applied to it, the goop will stay solid!
The second you let it rest, it liquefies and looks as if it's melting.
Try picking some up, rolling it in a ball, then let your hand lay flat.
Watch the goop stop being a solid and drip away!
Best part? The whole experiment cleans up with water.
