Smell of rain
That wonderful smell of rain that everyone loves is known as "Petrichor" This fantastic odor has been studied and analyzed by several scientists and even manufacturers of perfumes and aromas.
Petrichor is a Greek word, Petros, meaning stone, and the term ichor meaning, fluid that passes through the veins of the gods.
This unique fragrance that we feel when the rain falls and touches the ground is produced by bacteria present in the soil.
When you say you smell of wet earth, you are actually smelling a molecule that is being created by bacteria.
I particularly love the smell of wet earth, now let's say smell of molecules produced by soil bacteria.
