Our boat was made out of a 2-liter pop bottle. Morgan cut the side out of the bottle. That's where we added the battery for the boat. Next, we cut a hole in the bottom of the bottle for the wires and propeller to connect. After all that, we added blue tape to the bottle to make it look nicer. I also drew a big "M" on the side for our team name, Michigan.
We made many modifications in our boat. One modification would be the bottle. We were originally going to use a laundry detergent bottle, but it didn't work as well as the pop bottle.
