Ant Farm

I ordered an ant farm online, along with a tube of 25 ants. They're pretty cool to watch, but started dying off sooner than I expected. We got them on June 2nd, and we still have some alive, but they won't be for long - the info that came with the farm said the life span is 1-3 months (there is no queen). It was neat to do this once, but now sure if we'd try it again or not.
