Mr Bain told the class to build something that can move 20 meters or 20 feet and this is mine. We started with a plastic bottle made into a car that had a propeller, but it fell off the deck and broke. Then we had a plastic bag floating with candles, using heat, but the bag melted. We then tried a paper bag, but it was to heavy to float. Finally we tried to make a car out of wood and weight's and made it a pulley system.
