Lame Air Cannon Video

Re: BBC video clip of "vortex air cannon" ostensibly blowing down a brick house. The dweeb manning the cannon, when not talking excitedly to the camera, jumps up in the air when some bricks topple. It's a cheat, though--the bricks are stacked precariously in a house-shaped, single thickness wall, with no mortar.
Thank heaven the Huffington Post commenters are all over it:

That's bullshit. The bricks weren't mortared.

Too many Shows with dorks destroying things....

Two Words: Riot control.

Two more words: Closet organizer.

Two more words: Right on!
