Make Play Snow
In this science activity, kids will make play snow.
This activity is a fun way to stimulate imagination about the snowy, icy world of winter. Scientifically, however, this play snow has almost none of the qualities of real snow – it is not frozen, nor is it made of water. But it sure is fun to play with!
Pour the box of corn starch into a bowl. Squirt in the shaving cream until you have a light powdery substance that can be mashed into balls. This is messy, but great tactile fun for kids of all ages!
While you have the cornstarch out, be sure to make a small batch of "oobleck" by slowly adding water to the cornstarch. You'll notice it is very difficult to stir in the water because when you press with a spoon, the solution acts like a solid. But when you stop pressing, it goes back to flowing like a liquid. This is called a "non-Newtonian" fluid, because it only acts like a typical fluid under certain circumstances.
