I just watched the episode about the plane and I don't think that the myth was demonstrated correctly. The idea was to put the plane on a conveyor belt to keep the plane in one spot and see if the plane could lift verticaly.
If you watch the episode you can see that Jamie's truck did not match the speed of the plane because the plane was moving forward on the ground and then it took flight. Watch the episode again and you can see that the plane is moving forward on the ground because it passes several cones before take off.

I don't see a difference between freezing, cutting off the head or puncturing it, and letting it sit and just spraying it all around the car, although the second may be more scary.

the one with AB foam was nuts.

What does this have to do with shaving cream?

Their version of the tredmill is ridiculous, it applies forward motion to the airplane causing lift to the wings. On a conveyor belt there is no such applied motion. It is effect no different than attaching a glider to Jamies truck and dragging it down the airstrip untill liftoff, and this with no onboard propulsion whatsoever. The explanation that "How force is applied" is different from a plane to a vehicle has no bearing whatsoever on a treadmill. Matched velocities are just that, matched velocities.

I've done a similar prank when I was in college. But I didn't take the top of the can. I froze the shaving cream, hung it from the ceiling of another dorm room, poked a hole in the side and let it go.
It becomes a winter wonder land in no time.

The way I heard the Myth is, you freeze a can of shaving cream (the method was not specified) and then you are supposed to cut the can in half and throw the two halves into the car of the person you hate. Something to that effect.

Seems pretty dangerous to me, cutting the can in half and all.
I wasn't aware that they did an episode on this myth already...

Jeeze, why did I capitolize myth?
