Punkin Chunkin cannons... They use compressed air to shoot pumpkins almost a mile. American Chunker, below to the left, set the world record at 4694 feet. Sometimes the punkins cannot withstand the force produced by the release of all that compressed air in a millisecond and the pumpkin is vaporized as it exits the barrel.
Another source indicated that the Guinness world record shot is held by a pneumatic cannon dubbed "Big 10 Inch", at
5,545.43 feet (1,690.25 m), on September 9, 2010 in Moab, Utah. Apparently this distance was not sanctioned by the governing body of the Punkin Chunkers.
