My youngest brother had a Halloween party that they played "donut on a string" game that was a huge hit with the kids. Honestly the adults had a good time with it too.
Get glazed donuts or cake donuts, glazed holds up better we have found, and tie it to the end of a string. make the string long enough to meet someone's face/mouth if they were kneeling and hang it from a door way or the ceiling (we had a paneled ceiling in the great room back then, so a paper clip holding the string did quite nicely clipped onto one of the panel things). You can use tape too though, but it has to be strong tape!
The kids got on their knees and had 30 to 45 seconds (you can pick however long) to eat the donut without using hands (they must keep their hands behind their back). As you can imagine the donut swings around pretty good and you have somewhat limited reflexes while on your knees, so it's a challenging, very funny game. It brought tons of laughter!
The original suggestion on it said multiple kids should try to get to the donut at once, but we found that amounts to a lot of knocking heads.
