Antquarium is the original ant habitat created for zero gravity. Developed for a NASA space shuttle mission in 2000 to study animal behavior in space, the amazing nontoxic gel is both a home and food for ants. (The Antquarium's gel meets ASTM standards and is safe for kids.) What's more - the blue gel's transparency makes it easy to watch the ants digging their network of tunnels. A magnifying glass and ant catcher are enclosed (as well as instructions for ordering ants by mail - additional postage and handling required). Made in Italy of sturdy plastic, the Antquarium is 5" H x 3.5" W x 1" D. Fits in your hand, on a desk, or on a bookshelf. A fascinating and fun item.
