Over the last couple of weeks, I've noticed that, while playing with my daughter, we will suddenly veer into hard science. Earlier today, we were playing with Octonauts. The girl Octonauts were doing ballet. When their ballet instructor (a toy from another playset) had to leave, she summoned a black hole to travel back home.
This puzzles me. On the bright side, though, I now have a good answer if she ever asks where babies come from.
