Your last good ping-pong ball fell down into a narrow metal pipe imbedded in concrete one foot deep.
How can you get it out undamaged, if all the tools you have are your tennis paddle, your shoe-laces, and your plastic water bottle, which does not fit into the pipe?

All you have to do is pour some water into the pipe so that the ball swims up on the surface.

Edit:
oysterboy22's wording solution: none of those random things are going to help you, but the whole point is the person thinks they have to use the tools, while what they really have to do is urinate in the hole.
