Moon Sand
A non-Newtonian fluid is a substance that changes viscosity, such as ketchup. Ever notice how ketchup sticks to the bottom of the bottle one minute and comes sliding out the next?
Think of viscosity as the resistance stuff has to being smeared around. Water is “thin” (low viscosity); honey is “thick” (high viscosity). You are about to make a substance that is both (low and high viscosity), depending on what ratio you mix up. Feel free to mix up a larger batch then indicated in the video – we’ve heard from families that have mixed up an entire kiddie pool of this stuff!

Really nice how the sand can be liquid and solid!
My brother made it so hard that when you spilled it you spilled you could not get it off.

We have made something kind of like this but it did not have the sand.

The non-Newtonian fluid (just cornstarch and water) experiment was so very cool! Maybe even more cool than the moon sand! The kids and I just kept marveling how it would turn from a solid to a liquid right there in your hand. Who knew that there was more to cornstarch than just making gravy??
