In which D. abruptly acquires about 25 more pets

This evening we assembled the ant farm, with help from D's science project partner, SS. The ants were in a stupor at first, as I'd kept them in the fridge. I managed to get them all out of the vial and into the ant farm without incident, and they quickly woke up and went about their business. They've already decided which of the three tunnels to develop. The oddest thing I saw was that one ant picked up another (apparently blocking the tunnel), carried her a few inches distant, and dropped her, upon which she got up and wandered off in the other direction.
