Are you guys going to clean your pumpkins out BEFORE you go underwater? Or are you guys going to clean them out underwater? Underwater Pumpkin carving contests have gone on for over 30 years. Some of the local guys that have done it HIGHLY recommend cleaning out the pumpking before you go underwater then placing a lead weight inside to make it negative. I would hate to have a sharp object out trying to carve on something positive bouyant and muck up the viz with pumpking guts. Y U C K ! Wear a Hood to keep the mess out of your ears.
