Hold a Pumpkin Painting Contest
In fall, pumpkin carving is a big draw, but smaller kids are often left out because it involves using sharp implements like serrated knives. This year, instead of slicing those orange globes into scary shapes, hold a kid-focused pumpkin decorating day. With adult supervision, some stencils and inexpensive acrylic paints and brushes, kids can become master pumpkin crafters. This is less messy than a classic pumpkin carving contest, but the process is just as much fun. For the older kids and grownups, have a couple of face painting booths with pros on hand to do the honors.
We like the idea of performing this one outdoors, but if you're using a gym, cafeteria, warehouse or restaurant, put down some tarps to catch the drips. Don't fret too much, though. Everything will wash out with a little water.
