M.S.
Something I did at a party that keeps getting talked about - it was a dinner party with new co-workers, no one knowing each other yet, trying to get everyone comfy. In the middle of each table was a basket with 3-4 envelopes - in each envelope was a paper with a random question (what # child are you? what socks do you hate to throw away but never wear? if you had to wear a cast, what color would it be?). At any point, someone could grab an envelope and read the question - that person would answer it first, then everyone else at the table would follow.
One of the cards had a red star on the back of it, the person who chose that card got a special prize. There were kids ranging from 8-12, and the prize was a how-to-do-magic tricks book, that entertained the kids for the rest of the night.
Good luck!
