Beyond the link at the bottom of this here post is a video of two Russians from Dombay who jumped into a Zorb and daringly rolled it down a mountain. What is a a Zorb, you ask? Well it's a transparent ball big enough to fit humans in it. One of the Ruskies died when it ran off course and down the real-mountain part of the mountain. Now I know how my childhood hamster Weezy felt!
