How to Build a Rubber Band Powered Boat?

Answer

You can build a rubber band powered boat out of an Altoids tin, some rubberbands, two Popsicle sticks, and a piece of rectangular plastic. First either glue or use a large rubber band to secure the Popsicle sticks to the sides on the tin. Then make the propeller. Place a rubber band across the ends of the Popsicle sticks and then place a sheet of plastic in between them. Now wind it up and place the boat into the water.
