Cats and Buttered Bread: Rotational Dynamics and the
Anti-Gravity Machine

Abstract

In 1988 a machine which defied the laws of gravity was proposed. The idea takes advantage of the two well-known maxims: if
you drop buttered bread, it always lands butter-side down, and falling cats always land on their feet. Thus it was proposed that
maybe we can strap buttered bread to the back of a cat and drop it, and have it hover indefinitely due to both sides trying to
land face-downwards. The purpose of this talk is to show both theoretically and experimentally that cats indeed do land on
their feet and buttered bread does generally land butter-side down, due to the simple rotational dynamics involved. Besides the
cat trying to lick the butter off of its back, there are some obvious problems with the idea of joining the two together to create
the so-called anti-gravity machine.

Here is a cat and mouse fighting for your viewing enjoyment that doesn't have anything to do with physics or falling cats
