A coup de grâce in the office prank war; the pneumatic trash cannon prank:



Do not prank science nerds with access to modern machining equipment, they might retaliate. I love how the guys firing the cannon are wearing ear protection!

OMG! It blew him across the f-ing room!

[B-Man]

Yeah, that looks fake to me.

[green-lantern]

Yeah, that looks fake to me.

you do have to wonder

[onebadmollafolla]

There is no way that can be real. That guy was doing mach 5 across that room.

Bit high tech, you could just be a bunch of drunk Lithuanian mechanics...



I think we can guess who the apprentice is

Man, that could have damaged his balls.

Yeah, that looks fake to me.

Not fake!!! Here is how they did it:

After watching the long version, I still think the pneumatic prank is a fake. With the way they set this up, there is no way I can see to achieve that result the way they did. They're supposed to have used just air to knock him back (the styrofoam peanuts were just to have something blown out the tube). To have enough air pressure to blow a man back like that would have required a LOT of thrust. That much thrust would have blasted the tank backwards even harder than the guy.

The key though, is the victim's lab coat. A blast of air powerful enough to knock him back that hard would have blasted his coat back. You would have seen the coat flare out around him before he went flying back (simple physics of comparative mass, inertia and aerodynamics, not to mention I've played with air cannons before). The coat does the opposite. It wraps around him as he's knocked/pulled back.

If it had been some sort of projectile loaded in the barrel that knocked him back that way, it would have ruptured internal organs.

It's a fake, but quite a well made fake.

Agreed. The velocity at which he was thrown back is just not realistic. Plus all those other things you said.

like the guy who files an insurance claim that his car was broken into; only the glass was outside the car, not inside...
