My nieces & nephew love the donut on a string game. You run one long string horizontally from wall to wall (or tree to tree, as we do it.) Have the kids line up along the string. leaving a bit of space between. Tie a donut to a separate string in front of each child, adjusting it to about level with their mouth, and tying the other end to the horizontal line. Once every donut has been strung up, call start. Each kid has to keep his hands behind his back and try to eat the donut without using hands. The first one to finish is the "winner" but all of them like it because they get to eat the donuts! It's very funny to watch, but try not to use powdered donuts unless you want a group of tiny ghosts after!
