We take epic destruction and turn it into cutting-edge science. Featuring a man with a finger that can bash through coconuts, a car destroyed by a hose, a virtually indestructible Batman suit, and a 30-foot hand that can crush cars.

We're assembling a crack team of real-life superhumans: a home engineer who can walk on the ceiling, a knife nunchuck master, a diminutive arm-wrestler taking on a bodybuilder, and a man who can run a loop-the-loop.

Nature and science go head-to-head as we countdown the Internet's best videos. Featuring an amazing shark rescue, blood-sucking leeches, and a man who takes to the air armed only with a lawn chair, helium balloons -- and his shotgun.
