Video: White water rapids are Mother Nature's way of telling humans to find another route to their destination. Even with proper safety gear like a helmet and life jacket, navigating tumultuous currents like this is a risky thrill. But it gets exponentially more dangerous when you stack six rafts atop each other and attempt to shoot the rapids.
Using custom 2.7m-long oar extensions, professional rafter Covey Baack set sail for a series of class four rapids atop a Frankenstein-like creation that looks ready to tip at the smallest wave. But thanks to his skills, some physics we don't completely understand, and the ability of six inflatable rafts to absorb impacts, Covey managed to navigate the white waters without ending up in the drink.
