This thread reminds me of an idea from the old magazine, Omni:
When a cat is dropped, it always lands on its feet.
When toast is dropped, it always lands with the buttered side face down.
Therefore, it should be possible to strap buttered toast to the back of a cat such that the two will hover, spinning inches above the ground.
Given a sufficiently large buttered cat array, a high-speed monorail could easily be built to link New York with Chicago.
