Another observation that was made on the YouTube video that is in the article was that the size of the honeycombs are about the size of the bee. Apparently, the size of the honeycomb is proportional to the size of the bee. I thought that this was an interesting observation.
On a last note, for those of you who actually read this article, may I bring your attention to the credits on the hand-drawn pictures. I found it amusing and a little amazed that the pictures are by Krulwich. Nice pics, Krulwich! ;-)
