I waited an hour, then sent a single one-centimeter roamer in. No way an ant could piggy-back undetected on a roamer only slightly bigger than itself. The roamer picked up a couple of ants and brought them out of the hulk. I had prepared a couple of small coffins for the ants, filled with a plastic goop. The roamer stuffed the ants into the goop, then added the hardener. I now had ants under glass, more or less. While they might be able to cut their way out of those, I hoped they couldn’t do it before I completed a scan.
