PVC Tubing and Foam Provide Flotation |
In Part 2 they attempt to solve this problem with an electric drill mounted in the stern. Unfortunately, they have a very tiny propeller attached to the drill bit. It must have been the only propeller they could find. It doesn't generate much forward velocity, and eventually there is a catastrophic failure, which results in the bike sinking. They don't show the actual failure, just the aftermath with the bike in the water. Anyway, it's back to the drawing board for these two after this field trial.
