The paradox arises when one considers what would happen if one attached a piece of buttered toast (butter side up) to the back of a cat, then dropped the cat from a large height. The buttered cat paradox, submitted by artist John Frazee of Kingston, New York, won a 1993 OMNI magazine competition about paradoxes.
Some people jokingly maintain that the experiment will produce an anti-gravity effect. They propose that as the cat falls towards the ground, it will slow down and start to rotate, eventually reaching a steady state of hovering a short distance from the ground while rotating at high speed as both the buttered side of the toast and the cat’s feet attempt to land on the ground. In June 2003, Kimberly Miner won a Student Academy Award for her film Perpetual Motion. Miner based her film on a paper written by a high-school friend that explored the potential implications of the cat and buttered toast idea.
The faux paradox has captured the imagination of science-oriented humorists. Testing the theory is the main theme in an episode of the comic book strip Jack B. Quick, the title character seeks to test this theory, leading to the cat hovering above the ground, with the cat's wagging tail providing propulsion. The March 31, 2005, strip of the webcomic Bunny also explored the idea in the guise of a plan for a "Perpetual Motion MoggieToast 5k Power Generator", based on Sod's Law. In Science Askew, Donald E. Simanek comments on this phenomenon.
The idea appeared on the British panel game QI, where the idea was discussed. As well as talking about the idea, they also brought up other questions regarding the paradox. These included "Would it still work if you used margarine?", "Would it still work if you used I Can't Believe It's Not Butter?", and "What if the toast was covered in something that was not butter, but the cat thought it was butter?", the idea being that it would act like a placebo.
Cat righting reflex
In reality, cats do possess the ability to turn themselves right side up in mid-air if they should fall upside-down, known as the cat righting reflex.
