This is what happens when you leave your dad alone out in the woods with way too much time on his hands.
But it does look kinda fun.
Well...kinda walking on water. With a special mixture of water and cornstarch, you can create what is referred to as a "non-Newtonian fluid," which is basically a fluid that doesn't act like how a fluid should act...get it? Anyways, fill a 2,100 gallon pool of this stuff, and you'll have people walking, crawling, and dancing all over it!
