Fun with Colloids

My daughter likes chemistry, so I asked her to pick out an experiment she'd like to do. She picked colloids. We whipped up a batch of Goop for both kids and played all morning. My son refused to get his hands dirty, he hates the feeling, so he played carefully with a spoon.

Recipe: Makes enough for 1 child…..

1/2 cup cornstarch
1/4 cup water
small bowl, tin pie plate, etc.more water
Food coloring (if desired)

Add the water to the corn starch in a small bowl, tin pie plate, etc. Mix it together using your hands. If you need to add more water, add just a couple of drops (especially after playing with it for awhile).
