Oobleck

Earlier this year I did another fun 'science experiment' with my daughter for preschool.  This time we made Oobleck.  As in Oobleck from Dr. Suess.  It's a simple 2 ingredient mixture that turns to solid in a bowl but back into liquid in your hands.  Even I, the supposed adult in the situation, had a lot of fun playing with the stuff!

Ingredients:
1 1/2 to 2 cups cornstarch
1 cup water

Instructions:

1. Take 1 1/2 cups of cornstarch and add 1 cup of water.  Mix.  If the 'goo' isn't gooey enough, add a little more water.  Keep adding water until you have a consistency that is relatively easy to stir, but not runny.
2. This may look like a messy project but it cleans up very quickly with extra water
