Wheels made of bamboo

Bamboo like a "test tube" The "test tube" is made of a section of bamboo. (Bamboo is a grass). Mathematics can demonstrate that a slender pot has the best dimensions. That means that the pot should be like a test tube. Now, Nature has given the section of bamboo these dimensions. The distance between two joints and the diameter of the tube is the correct ratio to form a test tube. [55]
