A Ping-Pong Ball in a Hole - Back to the Logic Puzzles
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?

Why can't you just suck the ball out?

Sure, if you have lungs to suck it out of let's say 0.5 metre deep pipe

If the pipe was slightly wider than the ball (as stated in the puzzle) it would continue right through the pipe, so all you would have to do is go down to the bottom and get it from there.

NB: If the pipe had a closed end, it would not be a pipe, but a cylinder.....

Easy. Turn the pipe upside down, the ball will roll out ... it's called gravity

Although it was never specified, I believe it to be implied in the original challenge for the pipe to have a sealed bottom and was unable to turned upside down.

If the ball has not reached any elbow or bend in the pipe, and that this is a standard fuzzy tennis ball, then you can simply place a piece of Hook & Loop fastner to a stick and simply 'velcro' it out of the pipe.

Fill the pipe with water. The ball will float.
