COSMOS at BG

So COSMOS is a bunch of students and faculty who are big into science and math, and they do some really cool and fun science demos. Currently several of them are in the back of Dance Marathon showing some videos and doing small demonstrations. I just saw a cool video of a bunch of students walking on water. Yup, it's possible, if the right additives are in the water. Also, they showed a video of somebody lying on a bed of nails while getting a cinder block smashed on their chest. Because of pressure distribution, this is possible without any kind of injury. Isn't science cool?
