Petrichor

by Philip Junk

The term “petrichor” describes the unique scent of fresh rain on dry soil. Most of the smells you normally perceive hit you and disappear after a short period of time. But after heavy rainfall on a dry and warm ground, the whole surrounding is covered in a moist and cushioned atmosphere. The intensity of the scent doesn’t all of a sudden disapper, it rather decreases slowly.

Foam serves as a metaphor for petrichor. Just like the scent, it fills up every inch, every corner of a space and collapses slowly until it reaches its original state as a liquid.
