In the book, "Bartholomew and the Oobleck" by Dr. Seuss, the king of Didd wishes for something different to fall from the sky than rain or snow. Though no one is prepared for a sudden shower of Oobleck! Now you can make your own magical messy Oobleck at home.

Oobleck is similar to slime except it is made from cornstarch (also a polymer) and water. Investigate ooblek’s properties and try to decide if it is a solid or a liquid!

Materials Needed
* 2 cups of cornstarch
* 1 cup of water
* Green food coloring
* Sheet of wax paper

Mix together the cornstarch, water, and food coloring in a bowl. Pour a little onto the wax paper so you can play with it. Roll it between your hands and it feels solid, but let it sit and it becomes a gooey liquid.
