Crazy Messy Fun - Corn Starch Goo - Fun Summer Activities

Is it liquid? Is it solid? Is it fun?
The answer is YES! 
See for yourself with this simple recipe:

 1 cup part water
2 cups parts corn starch
(recipe can be halved, doubled, tripled....)

 Not only is it an excellent sensory activity ( perfect for the sensory table ) but it is also a science lesson! Why does it have both liquid and solid properties? Why does it feel firm if tapped quickly?  What does Non-newtonian mean?   Try to answer these questions and more as you squeeze, drip, scoop, and poke this mysterious substance.

You can even add food coloring to it for an extra goo-like appearance!
CLEAN UP: It is better to just let it dry and brush it off than to try to wash it off while it is still wet.
