Well, in our plan, we decided to make a square-like shape made with thick, cylinder rolls instead of triangles just to be a little different. To do this, we placed 3 rolls to face horizontally one way and then 3 across the other way. We didn’t have enough paper to make diagonal rolls. Though it looks a little rough, Sammy and I thought it was pretty strong… ==== ====The result, SQUASHED PIECES OF PAPER! The plan was to design a bridge that would support Mrs. Cs handbag which weighed 1.68kg or 1,680 grams. We think that the bridge collapsed because, unlike the middle which was thick and strong, the sides didn’t seem to be able to resist the weight and fell. Also, it could be true that squares aren’t the strongest shape. ====

Today Ms Charuckyj assigned some 5/6’s to build a bridge out of newspapers and masking tape. Our plan was to use as many triangles as we could. Our shape was horizontal, vertical, and diagonal. We made the supports to keep it strong. The newspapers were very weak so we would have to use more than 1 layer to make cylindrical tubes. It took a while to do and we made a big mess. The first time we put the handbag on it and it worked…=====

But then we tried again to make sure it was strong enough and it wasn’t the best, it was too wobbly but it was stronger in other ways because of the triangles that supported it.
