We built two structures. Our first structure was a little box with
pillars inside of the box. When Tony and I were putting the washers on,
some fell inside the box and we threw it in the trash. We built a new
structure and it was a cylinder. It held YunSang who weighs 126 pounds.
It also held 34 dictionaries because we put some pillars in the cylinder.
We changed our structure to a cylinder because our
first structure was weak!!!!!!! but our second structure was strong.
We put weight on the top of our structure.
I learned that index cards can hold any weight if the strong
structure is strong. It holds a lot of dictionaries.
