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.
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.
