The search for the most amazing adrenaline rush motivates people to do some pretty crazy things. Recently, daredevils created a human slingshot that launches base jumpers at speeds of over 125 MPH in just 1 second. The jumpers get the rush of a lifetime, and after they start to fall again, they quickly pull their chutes. Jumpers pull about 6 Gs on the launch from the 2 hydraulic cranes. If there has ever been a video to make your palms sweaty, this is it.
