Ants on the Ceiling?
Most districts would shut down any school that had insects crawling on its walls and ceiling, I hope. But, Uncle Milton’s Ant Farm Revolution can safely keep the ants under control while opening a new view on biology. The twist is that the kids can better watch the ants crawling through their tunnels, carrying large loads and generally just being ants because rather than a traditional rectangular ant farm, the Ant Revolution is cylindrical, has LED lighting and a lens so the ants’ movements can be focused on the ceiling. It requires three AAA batteries, comes with a bunch of ants and costs $40.
