Cameron has tried to obliterate the ball with the paper of the Bancroft and saw everyone. In 2013, Faf du Plessis slammed the ball in Zipper, or in the pocket of Michael Atharton in 1994, the ball was also running in the ball. All this is done to make one aspect of the ball rough.
Another way of ball tampering is to make an extra clean of the ball. This is the reason for the fielders to get rid of the ball. The teams now charge a number of people to smooth the direction of the ball using the spit. Their responsibility is to use the slip of the hand, using the trousers and spit and keep one side of the ball shining. Joe Root suffered a stomach ache following the test in 2016 in Chittagong. Draining of the field is not bad to wear the spit! But these are legitimate works.
The matter goes to the illegal level when artificial something is used to make the spit more effective. Due Platey was punished for a few minutes before the ball was shiny and shiny. Earlier, the English accused Zaheer Khan of using jelly beans. It has been heard several times in India's local cricket that Mennot's use of ball shiny has been used. All these things fall into the tampering phase.
