I think I may have accidentally invented a perpetual motion machine.
I was testing the veracity of various rules of Sod's Law, specifically the contentions that cats always land on their feet and that toast always lands buttered side down.
Experiment to test Sod's First and Second Laws of Motion
1 Take a slice of buttered toast.
2 Take a cat (male or female).
3 Strap the toast, buttered side up, to the back of the cat.
4 Drop the cat from a two-metre height.
The opposing Sod's Law forces suspended the cat and toast one metre from the ground in perpetual rotation.
Now, all I have to do is find a way of harnessing the energy created and I'm quids in. I suspect after they read this, Exxon, BP and Shell will be getting into the cat and toast market. This may push the price of thick-sliced bread and cat food up a bit, but you can't have everything.
