Description of Program:

One of the experiments for my STEAMPower Camp just didn't work and I had to find another program fast. This is an easy experiment that the kids will love. Oobleck is both a solid and a liquid as a non-newtonian fluid. They can shape it into a ball and watch it flow through their fingers when they release it.

Instructions:

*(modified from https://www.wikihow.com/Make-Oobleck)

  1. Add 8 oz of cornstarch to your aluminum tin.
  2. Add 4-5 drops of food coloring to water in a separate container, if you wish.
  3. Stir ½ cup of water into the cornstarch.
  4. Mix (works best by hand -- and kids love getting messy. Ask them to wear old T-shirts to this program.)
  5. If it starts to form, you're good. Otherwise, slowly add water and mix again until it forms.
  6. Experiment with the Oobleck. Once you're more comfortable with the substance, you should see what happens when you squeeze the goo hard, or when you let it sit for a minute before picking it up again.

Cost:

Cornstarch - ~$5 Grocery store or Amazon.

Aluminum pans - $1 Grocery store or Dollar Store

Food Dye

Miscellaneous:

A great STEM program as a drop in or with registration. Talk about states of matter and ask them if they've ever heard of it before.
Fun fact: Oobleck's name comes from a Dr. Seuss story!
