Ant farm
From Freepedia
An ant farm is an ant colony enclosed by a transparent box (usually made of glass or plastic). It is a registered trademark of Uncle Milton Industries Inc. Milton Levine is credited with creating the toy in 1956 after watching ants parade through a picnic. The company has sold over 20 million Ant Farms and is still family owned
They are usually made thin enough so the tunnels and cavities made by the ants can be seen, and for their behavior to be studied. Ant farms are popular "pets" for school projects.
