Miniaturizing ray

A miniaturizing ray or shrink ray, is any type of energy, such as a laser, that is projected from a ray gun, that is capable of shrinking matter. In most cases, a ray gun of this type would have at least two settings, one to shrink a target, and another to return it to its' normal size.

Brainiac's Proton Shrinker is a ray gun of this type, and he has used it to shrink the entire Kryptonian city of Kandor.

Doctor Hiram Gulliver also invented a shrink ray called a Sonic Microwave Reducer, which he used in an attempt to solve the Earth's growing population problem.
