Sure, people spend four years in college and maybe more in graduate school to get engineering degrees so they can work, teach, consult, and maybe even utilize their training and expertise to become expert witnesses. But, what do they do for fun?
They may spend their time designing a machine to propel an 8-10 pound pumpkin as far as possible. If so, they will be in southern Delaware this weekend for the 27th annual World Punkin Chunkin Championship.
In case you have not heard of this event, what began as four men devising a method to propel a pumpkin 126 feet in 1986 has now grown to a weekend event with nearly 100,000 visitors and 115 competing teams from across the U.S. While there is no prize money awarded, the bragging rights have provided enough incentive to elevate the engineering required to compete and win.
There are now several levels of competition, with the adult category having seven categories of propulsion: (compressed) air, centrifugal, catapult, trebuchet, human power, human power centrifugal, and torsion catapult. These categories are ripe for engineers - and any person with a technical bent – to provide creativity and ingenuity (including the use of components such as garage door springs and clotheslines).
However, all machines must meet required safety standards, and all pressure vessels must meet A.S.M.E. (American Society of Mechanical Engineers) construction codes, have the manufacturer’s nameplate, and be inspected by the Delaware Division of Boilers. The engineering and sophistication of these devices has produced the current world record of 4,483.51 feet (air category).
