This video just proves why you should never try gymnastics on concrete. I would be scared enough to hit a back flip into a pool full of cotton candy, but just straight up on pavement? Are you crazy or just stupid?

From the looks of this video I think this kid has more confidence that actual physical technique. He was really close but, no cigar.

If you think this is stupid you should see what happens when you try and skate down a slide with skates.
