This is how you make nerds a colloid:

1 cup cornstarch
1/2 cup water
Few drops of food coloring

(A colloid is tiny solid particles suspended in liquid.  Making a not-solid-not-liquid-and-definitely-not-gas.) 

This is B-rox trying to figure out how to "make it gassy too.  Then it could be a colloidas".
Eventually he came to the conclusion it can't be like air AND like a solid AND like water.  

When resting, this colloid acts as a liquid.
When agitated (rolled into a ball, tapped, stirred, etc.) it acts as a solid.
Mind bending. 

It does NOT taste good.
(Imagine that... but somethings you just have to discover for yourself.)

He's pretty stoked about science.  Why else would he have a pocket protector? 

Pretty fun "Scientists project".

Another fun scientist project: mix equal parts white glue and shaving cream. See what happens.

Shaving cream is my rather un-green go-to sensory project for any day!

Another fun thing is plunger painting. Get some clean plungers from the store and paint with them! My boys love it and it is great for big-body art!
