Why is saliva or sweat used for cricket ball

🤔 How it works ……..

How are clouds formed ?

Clouds are created when water vapour, an invisible gas, turns into liquid water droplets. These water droplets form on tiny particles, like dust, that are floating in the air. You hang up a wet towel and, when you come back, it’s dry.

In other words, we can say it is a process of evaporation followed by condensation causes the formation of clouds. Water present on the earth’s surface gets evaporated due to sunlight, and then rises up in the atmosphere. On reaching a certain height, water vapour present in air condenses to form tiny droplets of water. These water droplets collect to form clouds that float in air.

😳Why❓❓❓

Why is saliva or sweat used for cricket ball in matches?

The swing of the cricket ball is mainly governed by three factors namely shiny side, climatic conditions and behaviour of the pitch.

The cricket ball creates turbulence as it swings. The player uses sweat or saliva to make one side look shinier.
This helps to create challenging conditions to the batsman.
It is legal and allowed in all matches conducted by ICC. It is called ball tampering.
Ball Tampering is usually done after the ball wears away in the second half of a match.

There are two types of swinging namely conventional swinging and reverse swinging. During conventional swinging, the ball moves towards the side of greater turbulence. During reverse swinging, the ball swings the other side.
