In science class we have be making boats. This is my group boat. My group was Caleb H.,Austin, and Me. In the first time trial we did 7.73 seconds, that is 3 place in the grade. We used a piece of Styrofoam as the base then we rapped that in tin foil to seal it. We had straws off the side to keep it straight. The styrofoam cup and index card work as a sail to push it in the water. We had a fan that would simulate the wind.
