Each human carries trillions of bacteria in their bodies, and now you can carry one with your keys! This lovely little bacillus is a truly unique educational gift.
This bacterium opens up to show its internal structure in magnificent detail. One half depicts the structure of a typical gram negative bacterium, and the other side shows the internal structure of a typical gram positive bacterium. Gram staining is a venerable biological technique which reveals significant differences in the cell walls of bacteria. It has been an important diagnostic tool since the nineteenth century, and remains useful today.
