We must be out of our gourds! Don't toss out those post Halloween pumpkins or let them waste away on your porch. With the power of simple machine science like levers, wheels and axles, and pulleys, visitors can load them into the various WOW trebuchets and launch them down Sacramento Street! November 3rd from 10Am-3pm. General admission into the museum, $1 per launch and $2 to buy a pumpkin.
