Arrange the players in shuttle teams. Each player is given a tooth-pick and each team is given a ring (washer). At a given signal, the No.1 player tooth-pick in mouth, walks to the opposite line with the ring on his toothpick and gives it to No.2 player. The No.2 player goes back to the opposite line to give the ring to the No.3 player. The team that reaches its original position first wins the relay.
