According to former president Bill Sharp, the World Championship Punkin Chunkin Association was founded not only to "promote the concept that a pumpkin can fly," but to celebration "backyard ingenuity." In addition to the fun that they have, the Chunkers support various non-profit organizations and "present scholarships for higher education, in the fields of Engineering, Agriculture, Mechanical Technology and Sciences."
Medieval siege engines provide inspiration for many Chunkers, especially the trebuchet, which seems to be a popular design. Their website includes pictures from last year's event.
