Check Out a Huge Rube Goldberg Machine That Includes a Bunch of Crazy Stunts

Red Bull uploaded a crazy video to YouTube last week that's racking up a bunch of hits.  It's a Rube Goldberg machine (which is one of those chain-reaction machines) but this one also incorporates a bunch of STUNTS.

The craziest of the stunts start at 1:20. Don't miss the last big stunt at 2:40.

There's also a funny free-running video making the rounds, where a guy jumps from one roof to another.  But when he lands on the second roof . . . he crashes through it.
