Today we was make a structure it was a marble Roll and our design was a waterslide. My buddies were Caleb and Vinny. We used 5 pieces of big paper and 2 pieces of little paper, 1 metre of tape and scissors. Unfortunately our structure would not stand by itself, our tubes did not hold it. Next time, we could try and balance the tubes better and maybe add paper under it. Have you made a marble roll before?
