Beer crate climbing challenge

Out of all the quirky little competitions and challenges around the world, this has to be one in the top 5 or so! Crate stacking is a new sport game, where the objective is to stack as many upside-down plastic crates and transfer your footing without, you know, falling down. :)

Watch as a participant at a Polish festival stacks empty crates while maintaining his balance at the top of the stack. How high do you think you could go?

The best thing about crate climbing? It can be done anywhere, as long as there is an abundant supply of (beer or milk) crates to be assembled and an anchor point can be found, according to safety requirements.
