Stone jump out of water ?

  1. Apr 27, 2006 #1
    I have seen many of these phenomenon before that is when someone throw a stone to the water , the stone can jump out of water for several times before it drop to the water . I know it is due to surface tension of water .How do I know that what speed and what angle I need to throw the stone in order for it to jump from the water and what is the value of surface tension of water ?

    it is found that, a angle of 20 degree between the stone nd water,
    a speed of 12 m/s
    a rotational speed of 14 rev/sec of the stone, is necessary to jump on water..

    That is not true, it is not because of the surface tension.
