This is an improvement of the traditional round water pipe for better function of storage and usage. The square pipe is easier to hold and wouldnt be tangled like the round pipe. There are two grooves on one side, and two convex lines on the other side. Through fixing the grooves with convex lines, the pipe would become a disc. The storage would become convenient and it would not take much space.
