If we were about to jump off a cliff, we'd want safety nets, 81 different harnesses, four air bags and, ideally, a handy excuse to bottle-it at the last second.

Luckily, this dude is much less of a wimp. He uses the humble umbrella to combat the forces of gravity, flicking two fingers at Sir Isaac Newton as he did it.

Marshal Miller, Jesse Hall and Calvin Hecker found a 250 foot canyon in Utah, USA and thought it would be an ideal spot to set up a rope swing. They took the GoPros with them as well, so now we all get to feel our stomachs drop as they throw battle intuition and throw themselves into the waiting abyss .
