Mysteries

Here are some mysteries I know that I are pretty good.

1. Ok, there is a plane. Not an ordinary one. I bomber. An American bomber, flying in World War Two to bomb a city in Japan for bombing Pearl Harbor. The American pilot wants to drop two bombs down on to the village. He gets near the center of the village, and gets ready to press the button. Then he presses the button, the bay doors fall open, the bombs are released... But the bombs do not fall out of the plane to the city. How come?
2. A man bought a LOT of coconuts for five dollars each. Then he sold them ALL for five dollars each. As a result of this he became a millionaire. How come?
3. A horse is tied to a metal chain that he cannot break. The chain is forty feet long. There is a bale of hay ninety feet away. How can the horse get to the hay?

I know actually a handful of mysteries. So ya. That's that. So can you solve all of these? Any of these? Please comment something whether if you can solve all, one, two, or none of these. Thanks!
