Human cannonballs are designed to impress, mesmerize and fascinate the young at heart, what looks like a human being shot out of a huge cannon like a bullet from a gun is meant to be misleading. Propulsion for the stunt person is provided by a catapult, compressed air or a spring, if gunpowder is used it's only purpose is for noise and the smoke. The landings are generally in a net, large airbags and sometimes a body of water. Safety factors have been calculated to make the stunt as safe as possible, although safety issues have been considered the stunt still has a number of deaths to it's credit.
First, let's try stating the cannonball problem: Cannonballs are stacked in a square pyramid, with one on top, four on the level below, nine on the level below that, and so on, with n2 on the bottom level. If the total number of cannonballs is a square, how many levels are there? After the trivial answers of zero and one, the next answer is 24, since 12 + 22 + ... + 242 = 4900 = 702. It turns out that these are the only possible answers, but the proof is difficult.
