We have a bamboo stick in our humble home. It’s roughly 7’4″, and we use it to point at the whiteboard when we’re eating supper, discussing chemistry.

We thought it would be fun to measure the ratio between each of the segments’ length and diameter. Here is what we got:



 

As you can see, something very cool is happening to the ratio, which is in the farthest right column. First it’s 0.73, then in the middle it decreases, then it increases again to 0.74. Hopefully we’ll learn the reason for this someday.
