You cannot catch water? Reason.

Explanation:
It is commonly thought that water covers up fire and smothers it until it's out. This is not the case.
The real reason that water works so well on fire is that is has a great ability to absorb heat without turning to gas. This means that when applied to fire, it actually sucks the heat out of it and extinguishes it in that way.
To understand this, you need to have a basic understanding of how fire works.
In order for fire to burn, it needs three components: heat, fuel, and and oxidizer. In a typical campfire, your heat comes from the match you lit and stuck into the fire at the beginning, then subsequently comes from the fire itself. The fuel is the logs and twigs on the fire. And the oxidizer is the open air in which the fire is burning.
When you pour a bucket of water on the fire, the water sucks up the heat in the fire and removes one of the three sides of the triangle. Without heat, you've just got a couple logs and some air floating around, and thus no fire.
Answer:
As water is heavier than petrol therefore slips down permitting the petrol to rise to the surface and continue to burn. Besides, the existing temperature is so high that the water poured on the fire evaporates even before it can extinguisher the fire. The latter is true if small quantity water is poured. Thus the petrol fire cannot be extinguished by water.
