Pumpkin Chunkin' Relay is a silly, splashy game day at Children's Museum Houston in Houston, where teams race to fill pumpkins and then watch physics do its thing. Break up into teams, scramble to fill the pumpkins as fast as you can, and see which team gets the biggest SMASH when the pumpkins are dropped from a lift. It's a hands-on way to learn about gravity while laughing your way through the fall fun.
