Demolition Fail: Rock Flying At A Million Miles Per Hour Almost Smashes Guys Face [VIDEO]

A million miles per hour isn't the official speed of the rock, I just used that in the headline so you will watch this amazing video.  This is a demolition fail from the Czech Republic.  Check out how close that rock comes to hitting that guy in the face and almost takes a girls head clean off.  Astonishing that nobody was hurt, I'll certainly think twice before attending a building demolition party after watching this video.
