For three days, amateur scientists compete in one of four categories--air cannon, trebuchet, centrifugal force, or catapult--to see which team's device can launch a pumpkin the farthest. Nobel laureate and MIT professor Frank Wilczek explains the physics behind air cannons, trebuchets, and centrifugal force machines while event officials share the technologies they employ to determine launch distance. In interviews, air cannon teams share their strategies for hurling a pumpkin over four thousand feet in order to beat the world record.
