That's so cool! I have to try this with my kids. They will almost certainly not care, but what the hell.

Are you saying that a queen will die and its successor somehow knows how to use the door without learning like its mother had to?

No, the next generation queens grow in that swarm and learn it there. All swarm members learn it. To the queen (or the first few workers) you teach it. The rest learns from the others. But the workers are short living (few weeks). The queens live for about a year and can take knowledge in the next year.
