As the post-Halloween Jack Splat event at the Iowa Children's Museum goes on, great piles of broken and rotting gourds accumulate, shoved together with garbage-bag mops by the pumpkin pit crew. It's a joyful, odorous mess, and the crowd cheers especially loudly when an especially liquidy one goes splat.
A few days after Halloween each year, the Iowa Children's Museum hosts a wonderful event called "Jack Splat," in which children bring their rotting nasty pumpkins in and the staff hurls them off a balcony. Bringing up the fruits in ones, twos, and threes, the costumed MCs of the event read off each child's name, which method of execution they have requested ("straight down", "backflip" or "up in the air"), comment on the state of the pumpkin, and SPLAT! Down below, a crowd of children and adults of all ages cheers, and the pumpkin pit crew makes sure they stand behind the (semi-effective) splatter shields and shove the pumpkin remains off of the landing site into rough piles.
