Oobleck

2 Cups of Cornstarch
1 Cup of Water
Mix the two in a bowl. Add food coloring if desired.
Oobleck is a homogeneous mixture. It is a type of non-Newtonian fluid called a dilatant.
If you slowly lower your hand into oobleck, it will sink, but it is difficult to quickly remove your hand (without taking all the oobleck and its container with you).
If you squeeze or punch the oobleck, the starch particles will not move out of the way quickly, so the oobleck will feel solid.
Oobleck can be molded in a container, but when the mold is removed, the oobleck will lose its shape.

Mix 1/2 cup of Elmers Glue with 1/3 cup of water. Add a few drops of food coloring.
Separately dissolve 1/4 teaspoon of Borax in 1/3 cup of water. Stir until Borax dissolves.
