Remember Indiana Jones when that ginormous ball almost ran over our fearless (with the exception of snakes) hero? Watch this guy among others get run over by a gigantic hamster ball and laugh. This looks like fun! 

It's called Zorbing. You get into a gigantic hamster ball of air and water and roll down a hill. I've seen it and it looks like fun but i've never seen them run people over. This actually looks painful and scary but they have smiles on their faces.

I didn't find any Zorbs around here, so here is the closest one if you happen to be taking a Summer trip.
