Try your chances as you build a raft in the teams, with the ultimate goal of racing them across our pond, we know it sounds easy, but we've seen plenty of rafts float apart.

First you have the build phase, time to decide on your type of raft, then put it to the test on our lake...let's hope it floats...

You better know your knots and lashings when it comes to this one, or you'll be needing a towel quite quickly.
