Splatman

I heard the stupidest thing on the radio today.  Two PhD students in physics actually conducted a study, and concluded that if Batman were to jump off a 400ft building, he would die.  They apparently had the calculations to prove it, so who am I to argue.
I wonder what would happen if we took both of those guys up to the top of that 400ft building, tossed a  first edition Batman comic over the edge, and convinced them that whoever catches it first, gets to keep it.
