Bobbing For Apples, Ping-Pongs, and Golf Balls (game)
Pull up 3 guys and have a large fish tank (wider is better than deeper). Explain that it is time to play "Bobbing for Apples (name of your youth ministry) Style"! Instead of just apples put in ping-pong balls, small apples (like crab apples), and golf balls.
Explain that the ping pong balls are worth 1,000 points, the apples 2,000 points, and the golf balls 3,000 points. They will be blindfolded and have 30 seconds to 60 seconds each to get as many points a possible. (A great camp/convention promotion would be to put a $25 scholarship on the line). The visual on this one is hysterical. If your tank is big enough you may even try two at a time.
Other unusual things to "bob" for: oranges, hot dogs, pickles, eggs, etc.
