Drifting is to use the strength of the wrist to bounce the thrown stone on the water a few times. The result is based on the number of times the stone bounces on the water. The more times, the better.

The skill of throwing away water

First of all, material selection is very important. If you want to find a flat one like that, you'd better use tiles, hold it with your thumb and middle finger, and the index finger is at the back. When you throw it out, pull it out with your index finger and let it spin and throw it out. It's that simple.

The scientific principle of wasting water

The greater the flow rate, the smaller the hydraulic pressure.

Therefore, a relatively flat object (with a large stress area) should be thrown parallel to the water surface as soon as possible (to obtain a relatively fast flow velocity), which can drive the water above and below it to flow quickly in a very short time, thus reducing the pressure, while the water below is static, so the object can be pushed out of the water surface, and then the object will enter the water for the second time or more.

In addition, if the thrown object is rotating, it can achieve better results, because the water in contact with it becomes faster, thus reducing the pressure.
