 How this Works

You will Need:
1 cup cornstarch
1 cup measuring cup
1/2 cup size measuring cup
3-4 cup disposable plastic container with lid (Ziploc, Hefty or Glad make several sizes)
Food coloring (optional)
Plastic spoon
Water (4-8 ounces per group)
Old newspaper to cover your work surface

Step #1

Spread out the newspaper on the work surface
Obtain a large plastic bowl
Measure and pour in 1 cup of dry cornstarch
Add one drop of food coloring (if you wish)
Slowly add 1/2 cup of water
Use your fingers to mix until all the powder is wet
Keep adding water until the "Ookey Oozey" feels like a liquid

Now, try tapping on the surface with your finger or the back of a plastic spoon. When you have your "Ookey Oozey" made correctly, it won't splash. It will feel solid. If your "Ookey Oozey" is too powdery, add a little more water. If "Ookey Oozey" feels too wet, add cornstarch.

Step #2

Pick up a handful. Is it easy or hard?
Next, squeeze it. What happens?
Stop squeezing. What happens?
Slowly lower your fingers on the surface of the "Ookey Oozey"
Let your fingers rest on the surface
Slowly sink your fingers into the "Ookey Oozey"
Now, try to quickly pull your fingers out. What happens?
Next, take a blob in your hands, roll it between your hands and try to make a ball. What happens when you stop rolling it?

Please do not take "Ookey Oozey" home or out of the lab. Dispose of the product in a big sink using plenty of running water.  Enjoy.
