Stons skips several times if you project with 20 degree

You may have done this on your childhood or often now when you are alone and sittting by a pond . Guessed ? May be you know it , you might have thrown stone in the pond to bounce it several times. You might have played competition even with your friends who will have the stone for maximum bounces. The science that lies behind this trick is amazing.

If you want the stone to bounce the water for several times you have to project it at an angle of 20 degree. This angle of projection will make your stone bounce for several times. A Utah researcher has investigated how things and substance skips on water. The flatter the angle should be made, heavier the object is. It is also practised in military on throwing cannon balls and bullets.

Reseachers described about the combined complicated physics behind the mechanism of skipping a stone in the water. Hope the next time you skip a stone you can beat all your friends. Good Luck !
