The ever-innovative Japanese have created an ant farm with a nutrient-filled gel rather than the traditional dirt found in most ant farms. It turns out the ants can't function properly in the artificial goo, and end up dead in a short space of time. The Antquarium is great if you want to find who the most survival-worthy ant is, but pretty crap if you actually want to keep them as pets.
