I thought the Mythbusters proved that toast actually lands on the unbuttered side more often? I guess that's why any attempts to construct this failed - you have to attach the cat to the buttered side.
IIRC, Mythbusters found out that toast usually lands upside down when it falls off a table, but not when you drop it off a roof.
I think I'll go butter a toast on both sides. In the name of science and breakfast.
Since toast is generally shaped like a flat, semi-rigid slab, when it slides off of (your hand, plate, whatever), its center of mass falls off of the support and begins to descend before the trailing edge of the toast has cleared the thing from which it is falling off. In other words, the trailing edge of the toast gets "caught" on the edge of your hand/plate/whatever. This puts a torque on the toast, causing it to tumble. When falling from a typical height of 50-200 cm (i.e. the kind of height from which we would typically drop it onto the surface that we are standing upon), the toast has enough time to flip over once, so that the side that was formerly facing up will now be facing down. Since we tend to carry the toast butter-side up, this results in the toast landing butter-side down. Dropping the toast from a much greater height (e.g. the roof of a 2-floor building), would allow the toast to flip over more than once, and if it flips over an even number of times, then it will land butter-side up.
I always push dry toast off the table, onto a buttered floor, for maximum repeatability.
I think we are seeing the start of a buttered toast perpetual motion machine.
