Duct Tape Voyager

So a few weekends ago I notice that the Desert Breeze Park is going to have a cardboard regatta. You can make a boat out of cardboard and duct tape, and nothing else. I did not see it in time to put something together for the regatta, so instead I made one in my garage and threw it into my pool. It held me, and my daughters, for about half an hour before it fell to peices.
