Using large Jenga set - play a relay game
Large Jenga set - outdoor one is ideal
Split colony into teams. Place Jenga box in centre. When say go team members collect 1 Jenga piece (log) at a time bringing it back to their team before next member goes. Jenga pieces are piled up in alternating layers of three - building a lodge. Game finishes when box is empty. Count layers per team to decide winner. Play again in reverse - first make sure all lodges have an equal number then members return pieces to box - one at a time. First team to clear their lodge and sit in a line wins. Usually play at least 2 rounds.
