This is a big event in Delaware. A bunch of people have created machines to throw pumpkins—the rule is, the pumpkin must leave the machine still whole—and during the next three days, those machines will go head-to-head (well, um, metal-to-metal?) in a giant punkin-chunkin contest. Who will win with the farthest pumpkin throw?

You
can have your own miniature punkin chunkin day. Can you contrive a
machine that can throw a small pumpkin? Think large rubber bands
between two supports, or a catcher's mitt on a spring-lever, or a
sling that can spin and then release, or...?

Learn
how the Chunkin machines work here.
Instead
of chunkin punkins, perhaps you'd like to start off small. How about
building a catapult to hurl large marshmallows?
UPDATE: Hurricane Sandy dropped a lot of water on the Punkin Chunkin fields, and they are still a bit muddy. Organizers are going to set up today but not will hold the planned Friday events and machine practice runs.
