How do you you make a rubber band powered boat?
A rubber band boat works much like a rubber band airplane. First you need to build the boat itself. Then you need to make a propeller. The propeller shaft needs to run through the inside of the boat, not below the boat. With the prop below the water. The propeller shaft should not go the full length of the boat. About halfway through put a loop in the shaft. Then to the front of the boat attach a rubber band. Then run the rubber band through the loop in propeller shaft. Now twist the prop and the rubber band should twist around and around. When it's good and tight let go and the propeller should spin. Allowing the boat to move forward in the water. Mind you the shaft needs to be a thin piece of metal, as it will be difficult to make it water tight.
