Gravity

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!

German artist Cornelia Konrads creates these cool installations in public spaces, often using techniques and materials to give an otherworldly effect. Check out more in the via link!
