Shrinkers

Shrinkers is a term used primarily in science fiction and fantasy to describe devices, beings, or phenomena that reduce the size of objects or living organisms. It is a fictional concept; there is no verified real-world technology capable of shrinking matter. In many depictions, shrinking is reversible and comes with changes in perception, density, and interaction with the surrounding environment. The term is often used in contrast to amplifiers or enlargers and may serve as a plot device to explore scale-dependent challenges.

In fiction, shrinkers appear as handheld rays, laboratory contraptions, or magically invoked powers. The underlying mechanics vary widely: some stories treat shrinkage as simple spatial compression; others invoke alternate dimensions, altered physics, or nanotechnological processes. Consequences for shrunken characters or objects are equally diverse, ranging from susceptibility to heat and brittleness to changes in air flow, light, and gravity. Because of these inconsistencies, authors frequently establish their own rules to maintain internal coherence.

Notable examples include the 1989 film Honey, I Shrunk the Kids and its sequels, where a device randomly reduces people and objects; The Incredible Shrinking Man (1957) follows a man who steadily diminishes in size. In popular comics and cinema, Marvel's Ant-Man and The Wasp use Pym Particles to alter size while retaining mass, a concept that informs many related stories about power and vulnerability at different scales. Shrink-related devices also appear in video games, anime, and children's literature as a recurring gadget or quest element.
