Angelo Faticoni's Chair

Origin
Angelo Faticoni was a contortionist who went by the name “Human Cork” for his peculiar buoyancy. He discovered during his childhood that he was able to float for long periods of time, sometimes up to 8 or more hours. He has been fitted into a closed sack with a twenty-pound cannonball attached to it and would pop out of the water a few minutes later. When doctors examined him, they had him float in a tank for fifteen hours and could not decipher his ability, only hypothesizing he had unusual internal organs. He promised to reveal his secret but died before he was able to.

Effects
The chair is from when he tied a chair weighted with lead to himself and then swam the Hudson River. The lead is long gone and so is the rope that he was tied to it with. When the person is tied to the chair and dropped in deep enough water, they will be able to float for long amounts of time and with weight attached to them. The chair can be removed and the person will still float afterwards.
