Our artificial pyramid

After endeavor of two semester, we finally finish this small Pringlea Pyramid.

It is very not easy to establish. We must buy one or two every week.

The height of this 2D pyramid is about 1.6 meter.

It almost like a person's height.

Building it is extremely troublesome.

Because we open the door sometimes, it may hit it. And then collapse.

After we took this picture, we decided to discard it ><".
