Found this really cool trick on YouTube in which a pool player hits a pool ball in the pocket corner and hits a domino which starts a chain reaction of dominoes tumbling and along the way, the dominoes knock in other pool balls. A very cool trick, the video clip is in French but you do not need any translation to understand the trick and what is going on so do not worry if you do not speak it, just watch the clip anyways because I am sure you will be amazed.
