For our boat project we made our boat out of styrofoam and tinfoil and tape. We had a sail that was attached to popsicle sticks and it worked very well. It went fast. There were popsicle sticks to keep it straight. We will put more tape on the popsicle sticks, because yesterday the tape got wet. We’re going to add more weight to the back. I hope that our boat will do better than yesterday. I hope we will win.
