We've all been there. How many times have you been frustrated by a car that won't start, a computer that locks up, a vending machine that won't drop your food or a DeLorean that won't take you 'back to the future'?

Since most of us don't have mechanical or engineering degrees, usually the first option is to give the troubled item a swift kick or a decent fist bump. Does that ever work? Sometimes. However it almost always works in the movies and on television. If you don't believe me, check out this clever video featuring clips of 'percussive maintenance'. (And if for some reason the video freezes up on you while you're watching it... you know what to do).
