There's no reason to be so hostile in this thread, I do admit however that some of the jokes in this thread (hint hint) might be a little much, but it's no reason to use swears (not that drew's word filter doesn't catch them, but still.)
With the plastic wrap, I'd be worried about over-heating the test-tubes, esp. if left in sunlight. Almost looks like one of those craft microwaves you can make with tinfoil..... I would suggest putting them in the dark, and perhaps away from normal activities since it looks to be in the living room area, where someone could potentially damage the ants or disturb them.
