Our idea was to make a sail boat. The tupperware and tinfoil on the back is a weight so it doesn’t tip over. The straws on the side so in glide on the edge of the track easier and the sail to catch the wind and go faster. On our first trail we got 3rd place with 8.83 as our time. We made a few changes with the sail because it was very small and didn’t go as fast as we wanted. I hope be fixing the sail it will move faster and smother.
