    Default Water doesn't just drop, it bounces

    I wasn't aware of it until I saw this video.

    See how water drop bounces when the video is shoot at 2000 frames per second...

    At 1:17, did I heard wrongly from the narrator: "For the non Phd"?

    Yes, the narrator meant 'for the lay-men.'

    That is simple awesome! A very beautiful discovery! Well for a non PhD like me, it is simple enough to understand the explanation given. It would have turned into a very beautiful shot if captured.
    Your pictures speaks for you, not your camera.
