Mystery Box Auction - Ask for wrapped package donations (big or small) e.g theater tickets, baked goods, electrical appliances etc. As each box is brought in, label it with a number and place on tables that have been set up. People will be allowed to examine the boxes, picking them up and shaking them. Absolutely no unwrapping or peaking! Run the auction with a live auctioneer or silent auction. Let each winner unwrap their box in front of everyone.
