We had to make boats out of various materials for a lab in science. Ours is made out of tinfoil, an index card, part of a styrofoam cup, and some straws and tape. We also have a balloon on the bottom of the boat. We mainly used hot clue to keep it together. By we, I mean me and Kallie, because she was my partner. We originally had a mast, but it kept falling. That made it so the boat couldn’t go. Kallie came up with the idea of sticking the sail ti the straws. All in all, our boat goes ok, but not the best. Whatever, we had fun making it.
