OObleck

Is it a solid or liquid????

Pair this experiment with reading Dr. Suess’s Bartholomew and the Oobleck.

 (Check it out from the library.)

(Use 2:1 cornstarch to water)

2 Cups of Cornstarch

1 Cup of water

(if it is not mixing, gradually add a little more water ~1/4 cup.)

Optional:  If you are reading Dr. Suess add a couple of drops of green food coloring.  BE CAREFUL the food coloring can stain.

Answer: 

It acts like a liquid when poured but a solid when a force is acting on it, such as squeezing it.
