In science we had to design boats with only materials that we were given. After we had built our boat we had to do 2 time trials. After the first trial we could make changes to our boat. Our boat was made out of straws that were use on the sides with a peace of foam in the middle used to keep it a float. The mast was made out of a pop-stick that was glued to the boat. The sail was made out of 2 pieces of index card glued together. The winning time for our boat was 7.71 seconds.
