[Solved] A ping pong ball fell down into a narrow metal pipe embedded in concrete one foot deep. You have a table tennis racket (bat or paddle), a pair of shoe laces and a large unopened water bottle, which does not fit into the pipe. How can you get the ping pong ball out of the pipe undamaged?

This riddle has been around for some time on internet platforms such as Instagram, Facebook, and WhatsApp, and many people still argue over what the answer might be, as there are many possibilities. The correct answer is Ping pong balls float on water. So, pour the water from the water bottle into the pipe till the ping pong ball floats to the surface.
