This nerdiest and most ubiquitous physics joke is amusing to everyone but the cat! Colorful enamel pins feature "alive" and "dead" versions of Superposition Cat from the classic quantum mechanics thought experiment. Wear them together or mix & match.
Each pin is about 1.25 inches wide with rubber pin backs. Designed in Brooklyn, NY, USA, made in China.
