Something about our boat was that our first time was 8.18 seconds. How we built the boat was like two skeis on the bottom. then put craft sticks to hold it together. Then we put the cup on top so the wind from the fan would get caught and push it. My group was Allie, Emma, and me. We tied to change some stuff, but it always made it slow down. So we are keeping it the same for the 2nd. time.
