Every now and again a person needs to be entertained by stupid people doing stupid stuff.
I jumped onto YouTube just so I could enjoy some videos of stupid people doing stupid stuff I stopped after I saw this one. There was nowhere else to go but down and while this girl didn't get hurt, she could have.
Slingshot - Simple enough. Giant rubber bands connected to poles or trees with a human being strapped into the middle. I gotta tell you, this makes bungie jumping look like a merry-go-round when you think about what could happen if only one of the straps broke. Because a bungie rope will likely snap at full stretch and the fall will be big, but this is insane.
