When Scott is first figuring out how to work with Pym's ant colony, he is naturally astounded at what he's seeing, most of all the fact that Pym has attached a miniature camera onto one of the ants in order to keep track of what's going on. It's one of the movie's more hilariously absurd moments, a "well, that happened" aside that, given the premise, is easy enough to just go along with.
