The smell of rain has been very prevalent this month - every day, it seems like. For a lot of us, that smell reminds us of the days when we'd splash in puddles as kids, or stay dry inside while helping mom bake cookies.

But did you know the smell of rain is not actually rain itself?

Social Meteorologist Matt Makens (at least, that's what I think his title should be *ba-dum-ch!*) shared a video explaining the phenomenon known as petrichor, which is what we're really smelling when it rains.

"Apparently plants, vegetation give out these oils when the weather is dry, and those oils work into the soil and rocks nearby and is like a suppressant for growth for the plants and stop seeds from germinating," Matt says in the video below, originally posted to his Facebook page. "Clearly, you want that when the weather is dry. But when the rain starts to move in..."

Watch Matt's video above for his awesome explanation on the science of the smell of rain! (And seriously, he should call himself a "Social Meteorologist" because he's very active on Facebook and Twitter.)
