The Shrinking Machne was a machine created by Gyro Gearloose within a dream Scrooge McDuck once had; its existence (or indeed feasibility) in the “real world” is uncertain.
Description[]
Within a dream Scrooge McDuck had in 1983, the Shrinking Machine was a large machine built by Gyro Gearloose to enable Scrooge and his nephew to enact “Operation Leaf” by shrinking themselves and exploring the microcosm inside the cells of an ordinary oak leaf, so as to pierce the secrets of photosynthesis and bring them back to the macro-scale world to be applied as a new source of energy.
Behind the scenes[]
The Shrinking Machine first appeared in the 1983 story Plantastic Voyage.
