Ant Farm-- of the FUTURE

This is a neat little variation on the traditional ant farm; ditch the sand (of volcanic pumice that they use these days) and replace it with an aqua-blue edible gel that the ants can not only tunnel through, but eat as well. Add some blue LED lights for that high-tech touch and you're set.

The ants, unfortunately, are still just ants, so you'll have to deal with that on your own.
