The idea is to build the cardboard boxes up, then seal them in plastic bags, and use these boouyancy 'blocks' tp build a raft. In practice, of the three teams who attempted it, only one got their 'sailor' safely across the pool. Here are the two unsuccessful teams at their moment of immersion:
The first team built a raft that had good, solid boxes, well tied together. However, they built a narrow raft which had very poor stability, and despite a few attempts, the raft was unable to remain upright.
The second team distributed the bouyancy more evenly, but one of their boxes failed around halfway through:
The third team, pictured at the top of the post, managed to get across without any incident. I allocated 45 minutes for this, and all three teams had sufficient time, even allowing for around half the team being unfamiliar with raft building. I can recommend this as a patrol challenge if the weather is good. I would suggest having a full set of boxes for each team- in the event that a box gets wet, it is almost impossible to re-use.
