Miniaturization doesn't actually make sense unless you miniaturize the very atoms of which matter is composed. Otherwise a tiny brain in a man the size of an insect, composed of normal atoms, is composed of too few atoms for the miniaturized man to be any more intelligent than the ant. Also, miniaturizing atoms is impossible according to the rules of quantum mechanics.
Depending on how those atoms were supposed to have been miniaturized, the man might or might not also weigh as much as he originally had; an observation that has been used to various effect over the years in media such as comic books.
The problems of the miniaturized human do not stop there, however. Basic geometry governs such things as the relationship between cross-section, volume, and surface area. It may be impossible for a one-inch high human to kill themselves in a fall of any conceivable height, but they may be able to drown themselves with a single drop of water.
Appearances in popular culture
Films and television
- Dr. Cyclops from the 1940 horror film of that name shrank his victims by locking them inside an "atomic generator".
- In the 1958 movie Attack of the Puppet People, a scientist captures people and shrinks them to 6 inches in height with an ultrasonic wave device, so he can keep them as company. (He keeps them sealed inside special suspended animation canisters between "puppet shows".)
- The 1966 science-fiction film Fantastic Voyage (written by Harry Kleiner, novelization by Isaac Asimov) is plotted around such a device, allowing the miniaturized submarine Proteus to carry a crew inside a stricken scientist in an attempt to save his life. They have one hour to cure him before they expand back to normal size.
- In the episode "The Big Break-In" of the 1987 Teenage Mutant Ninja Turtles animated TV series, Krang uses a remote-controlled minimizer device with a shrink ray to shrink down US Army bases, preventing them from attacking the Technodrome. In the episode "Funny, They Shrunk Michelangelo" of the same TV series captain Talbot Breech uses a miniaturizing ray to shrink US naval ships and put them into bottles as revenge on those who turned him down for the US Naval Academy. The same show also features the episode "Poor Little Rich Turtle" features Shredder using a shrink ray on the girl Buffy Shellhammer, who despite her young age runs a company, to force her telling a super rocket fuel formula her grandfather told her before he died.
- In The Penguins of Madagascar episode "Jiggles", Kowalski uses his shrink ray to shrink Jiggles to normal size.
- In an episode "Getting Antsy" of the 1991 Darkwing Duck cartoon, a villain Lilliput uses the ray to shrink buildings and landmarks of the fictional city St. Canard. He then employs ants to haul the shrunken buildings to a miniature golf, where they become part of the course. Eventually, Lilliput also shrinks the hero Darkwing Duck to an even tinier size.
- In an episode of Codename: Kids Next Door, titled Operation: M.I.N.I.G.O.L.F., after Numbuh 2 bests champion golfer, Rupert Putkin, in a game of mini-golf, Rupert seeks revenge. He builds a shrink ray to shrink down the world's greatest monuments and uses them in his own miniature-golf course. Afterwards, he shrinks Numbuh 2 and forces him to play a rematch in his smaller height. Later, Rupert plans to use Numbuh 2 as the golfball as he hits him into a hole that will activate his shrink ray to shrink the world. His plan fails when he misses and Numbuh 2 hits the reverse setting on the shrink ray, which zaps Rupert and makes him grow bigger, causing him to step on and crush his golf course. The shrink ray is destroyed subsequently, but Numbuh 2 remains tiny. He runs back to his friends in the treehouse, and they use him for ping-pong.
- In another episode of Kids Next Door, entitled "Operation: S.P.R.O.U.T.", when Numbuh 4 swallows a brussel sprout, supposedly to make him an adult faster, his friends at Sector V take action. Numbuhs 1, 2, and 5 use a shrink ray to shrink down to the size of a booger. Afterwards, Numbuh 3 places them inside of Numbuh 4's nose, and they make their way to the stomach to recover the brussel sprout, before the shrink effect wears off. They are able to retrieve the massive sprout and make it out of Numbuh 4's body just before they re-expand to normal size. In the aftermath, Numbuh 4 returns home and accidentally eats liver, implying that they have to go on the same mission again.
- In the TV series, The Adventures of Jimmy Neutron: Boy Genius, one of Jimmy's most-used inventions is his shrink ray, first introduced in his film in which he shrank himself in order to sneak out of his house.
- In the 1996 Tim Burton's movie, Mars Attacks, the Martian Leader uses a shrinking ray to shrink and crush the President of the United States' main general, General Decker.
- In "In the Belly of the Boss", the third segment of The Simpsons Halloween special episode "Treehouse of Horror XV", the Simpson family is shrunk by Professor Frink.
- A shrink ray invented by Professor Wayne Szalinski is featured throughout the Honey, I Shrunk the Kids franchise, and is the primary invention used throughout. Not only could it shrink people or other objects, but it could also reverse the effect to bring them back to normal size.
- In a 1995 episode of Captain Planet and the Planeteers called "No Small Problem", Dr. Blight invents a shrinking ray which Sly Sludge uses to shrink rubbish.

- In Doctor Who, the Master uses a Tissue Compression Eliminator to shrink and kill people.
- In Lilo & Stitch: The Series, Dr. Jumba Jookiba invents a shrink ray that can both shrink and enlarge objects. This device is used in "Poxy" to shrink Lilo and Stitch in the X-Buggy to get into Pleakley to retrieve a microscopic experiment (Experiment 222/Poxy) that makes people ill. Gantu is also shrunk down by the same device in the episode. In "Short Stuff", the same device is used to enlarge Stitch to become big enough to ride a roller coaster, but he's accidentally made into a giant and thus too big to ride the coaster. The episode's experiment (Experiment 297/Shortstuff) is also enlarged by the device, getting into a fight and winning against Stitch at the fair. Stitch is brought back to his regular size to defeat the experiment. Gantu also used the device to enlarge Experiment 625.
- Two episodes of the Lilo & Stitch anime spin-off series Stitch! feature Experiment 001/Shrink, an experiment first introduced in the Lilo & Stitch: The Series finale film Leroy & Stitch (as a cameo), as a rare example of a living creature (albeit an artificial lifeform) being a shrink ray. In the episode "Shrink", the experiment shrinks several characters to a smaller size until he returns them to their regular sizes, although at the end of the episode he instead grows the alien BooGoo to become larger than the planet Earth. In "Experiment-A-Palooza", Shrink grows Stitch into a giant who is also reverted to his former destructive programming thanks to the abilities of Experiment 210/Retro.
- In the Aqua Teen Hunger Force episode "Unremarkable Voyage", Frylock builds a shrink ray (which can also enlarge items). Master Shake quickly gains control of the machine and proceeds to abuse its power for his own benefit. The shrink ray turns out to be faulty, however, as shrunken items return to normal size after a period of time.
- A shrink ray is a recurring device shown in Venture Brothers, although it never seems to actually work properly.
- In Despicable Me, Gru used the shrink ray to shrink the Moon and pocket it. The effects of the shrink ray are only temporary, however, and the bigger the mass of an object, the quicker the effect wears off; this is called the "Nefario Principle". Vector returns the Moon to satellite orbit before it returns to normal size using his escape pod, but the Moon expands before he could do so in time and his escape pod is consequently destroyed, trapping him and a Minion on the now normal-sized Moon.
- In Innerspace, a naval aviator is selected as a guinea pig to participate in a project which places him in a submersible pod to be shrunk to microscopic size and injected into the body of a rabbit.
- In Gravity Falls, Dipper Pines was insulted by his twin Mabel Pines, so he finds a crystal that he attaches to a flashlight. One side enlarges things and the other shrinks things. It falls into Gideon's hands until the twins stop Gideon from shrinking Grunkle Stan and taking the Mystery Shack.
- In Dragon Ball, a Micro Band invented by Bulma can shrink its wearer. Also, a portable home called a Capsule House can be carried around in a capsule and deployed when desired.
