This ant habitat allows one to study the behavior of ants in a unique, self-contained environment. Its special gel is full of nutrients specially formulated for the needs of the ant. Because the gel is clear, one can see tunnel architecture develop in 3-D - offering a new and unique perspective from that of the traditional, soil-based habitats. This habitat includes a container with a special gel formulation, magnifying glass, 20 page booklet detailing fascinating ant facts, and a special 'extreme magnification lens' with which one can even see hairs on the ants!
