We created boats made out of Styrofoam, paper, Popsicle sticks and straws and other things. It was a fun project and are boat was fast the day before the race day then on race day it was on a angle and got stuck so we got d.n.f. which means did not finish. the after the first race we improved are boat so it would not get stuck and are next race we go 8.83 seconds. so the one thing i learned was after a failure improve and you will succeed.
