Once again, acclaimed YouTube director Devin Graham has invented a new activity that looks incredibly fun, if not pretty dangerous.
For his most recent video, Graham built an enormous bowling alley in the mountains of Mammoth, Calif. He added a giant, inflatable bowling ball that is big enough for a person to sit in. Think of it as a hamster wheel for humans.
Once in the ball, the bowler rolls down the hill and crashes into several inflatable pins. To make things more interesting, another person can start in front of the bowling ball and try to beat it down the hill before getting bowled over. More often than not, that person finds him or herself bulldozed by the ball.
Looks great, but for safety reasons we'll stick with the homemade water slide.
