A beekeeper did something simple: he put a bell jar over an opening in his beehive. The bees obliged by building a hive within it, where you could see it, and captured the process in a series of photos.
I’m fascinated by the fact that the first struts in the framework are regularly spaced vertical bars of wax — how did they do that? I want to see videos of those early stages when the bees are working to initiate the strips. I suspect there are some interesting bee:bee interactions going on as they set them up.
