Give each team a fifteen-foot piece of string with a sliding paper cup on the string. The string is held tight (works good if you tie it to a chair) and the paper cup is placed at one end. The team lines up single file. At the signal, each player must blow the cup to the other end (with hands behind his/her back) and then push it back to the start for the next player. The first team to finish wins.
