The Shrink Ray is a shrinking ray-emitting machine found in the Hall of Science.
Description[]
Showcased in 2014 at a Hall of Science, and deemed by Ludwig von Drake to be one of the finest inventions of the 21st century, the Shrink Ray is a bulky machine with the ability to shrink down living beings to minuscule size for a few minutes, without hampering their health or their ability to move about. Though the Ray wears off quickly, it contains a safeguard against the danger of "reinflating" in a small enclosed space, as it materializes a protective, egg-like "shell" around its targets as they grow back to their own size.
Behind the scenes[]
The Ray appears in the 2014 Mickey Mouse: The Series cartoon, Down the Hatch.
While it would be easy to assume that the Shrink Ray is an invention of Ludwig von Drake himself (who frequently bragged about his own inventions showcased in the Hall of Science), nothing in the cartoon states firmly that it is so.
