    A Ping-Pong Ball in a Hole

    A Ping-Pong Ball in a Hole

    A table tennis ball (= ping pong ball) fell into a tight deep pipe (amendment: eg. 30 cm) long, buried in concrete pavement - having firm metal bottom, only 1 cm of the pipe is above the ground - so it can not be moved). The pipe was only a bit wider than the ball, so you can not use your hand. How would you take it out, with no damage?
    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?



    Ball in a Hole - Solution:


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