I love this diagram.
Get a cat. Cats always land on their feet...
Get buttered toast. The buttered side will always hit the ground first....
Attach the toast to the back of the cat so the non-buttered side is touching the cat.
Drop the cat from any height.
The infinite force engine and anti-gravity engine are created, since the cat can't land on its back and the buttered toast is on the cat's back and has to land first.
Somehow... the cat eats the toast.
Cat folds in on itself.
You now have a wormhole. Enjoy!
