A flat stone can jump over the water surface fifty-one times. This is considered a world record, but you can achieve this by remembering the recipe for making pancakes on the water.

Firstly, so that the stone does not sink for a long time, you need to throw it as hard as possible. The fact is that on the water any body holds the so-called dynamic force. The smaller the force of motion, the less dynamic force. This pattern is used by water skiers.

To cook more pancakes on the water, you need to throw a stone along a special path. If the stone falls into the water at the wrong angle, it will immediately drown. The stone should fly as close to the water as possible, so you will achieve a better rebound. The correct low-throw technique can only be achieved by training muscle memory. To do this, it is recommended to throw the puck under the low bar.

To determine the "golden" angle of the splashdown stone, French physicists used a camera with accelerated recording. Their experiment showed that if the projectile is brought down by a wide surface, and even at an angle of twenty degrees, its rebound will be ideal.

One more tip. Remember, the projectile must rotate. When throwing, the stone must be held between the middle and thumb. A forefinger, ask him to rotate. The fact is that after the first bounce, the projectile loses stability in flight and the next time it touches the water surface, the angle between the stone and the water can be unpredictable. And if the stone rotates, then due to the gyroscopic effect, it maintains a stable position in flight. This effect can be observed when the spinning top starts, while it is spinning, it will never fall.

The main ingredient in this recipe is a regular-shaped stone. Nature has created different pebbles, but for jumping on water, like no other, they will go flat and round. The larger the diameter of the stone, the better it will jump on the water. However, a large naked will not work, he is heavy and will quickly drown. The golden mean is a stone with a diameter of ten centimeters. Such a stone will weigh about a hundred grams and among physicists it is considered optimal.

Throwing stones on water in America is called stoutne skipeng. And the world record, fifty-one times, also belongs to the American. And the first official record for a stone skipeng is twenty-two pancakes.
