Finding: BUSTED

Explanation: Like many fan requests sent to the MythBusters, the question of whether you can unlock a car with a tennis ball came straight from a viral video on the Web. If seeing is believing, you could cut a small hole in a tennis ball and pick a car lock by pressing the ball over the lock and giving the ball a hearty squeeze. The theory is that the air pressure released from inside the tennis ball can supposedly force the mechanism to release.

MythBusters Kari Byron, Tory Belleci and Grant Imahara took a shot at the tennis-ball trick with different sized holes in tennis balls but failed to pick any locks. In case the air pressure inside the tennis balls simply wasn't sufficient, they even tried vacuum-sealing the car lock and applying 100 psi of air pressure (about nine times the normal atmospheric pressure) to it.

But even the pumped-up pressure couldn't score a point for this myth. And with the tennis ball lock-pick trick busted, the match went to the MythBusters.
