For a team of players to safely stay on a shrinking island.
One tarp per 5-12 players
A group of 5-10 players stand on a tarp.
On the leader's signal to begin all players stand on their tarp.
The leader then asks the group to remove half of the island while all the players stay positioned on the island, not stepping into shark invested waters off the island.
Continue cutting the island in half. At some point it will not be possible to remain on the island so the leader says there are 30 seconds while the sharks are away to step into the water, reduce the island size by half, and get back on the island.
-Questions & Notes:
Safety: do not permit players to sit on other player's shoulders.
Discuss: How did the teams determine how to best meet the challenge?
