watch the above until 1:08, then see below. (or watch as much as you like, but if you want to save time, and not waste it, I've pointed out the only significant portion of the video)



and watch until 2:42. Then tell me, didn't you also say "what the fuck?" especially after the floaty demonstration at 2:30
