This is the coolest ant farm. We got it for Jingju for Christmas, but just set it up yesterday. It's based upon a 2003 NASA Space Shuttle experiment to study animal life in space and test how insects-ants, successfully tunnel in microgravity. It's filled with a gel that's complete with nutrients to promote healthy growth in the ant colony, and means you never have to give the ants food or water. It also lights up! It's available at Amazon.
