today i learned – sun 30th dec 2018

feels like we’ve not had rain in ages ๐Ÿ˜ข i quite miss the smell … ever wondered where it comes from?

#tdil that rain smells good due to a number of different elements such as ozone and plant oils!

apparently, the smell only happens after the first storm that’s happened in a while … which means we could verb possibly have it coming soon ๐Ÿ˜

anyway, the reason for the lovely scent (that has inspired many a candle) is actually a number of different things ๐Ÿ‘๐Ÿป

the first of these things is plant oils ๐ŸŒท during periods of little rain, some plants excrete oils that soak into the soil and rocks. when the rain finally comes again, it mixes these oils and causes them to release some goodness into the air ๐Ÿ˜

the second element that combines with the plant oils and helps with the smell is bacteria. more precisely, itโ€™s often a bacteria called โ€˜actinomycetesโ€™ because it creates a substance named โ€˜geosminโ€™.

the third element in this rainy mixing pot is ozone ๐ŸŒŽ – its particularly plays its role after thunderstorms โšก๏ธ. ozone is a molecule that consists of three oxygen atoms bonded together (hence it being called o3).

during periods of lightning, the mad angry electric arrows that fly from the sky can split the oxygen and nitrogen molecules … causing them to recombine into nitric oxide (no). no can then interact with other chemicals in the atmosphere to produce ozone … ozone smells ๐Ÿ‘๐Ÿป sometimes a little like chlorine ๐Ÿ™ƒ.

and there you go! three things that contribute to the beautiful smell of rain ๐Ÿ˜ … of course, there are a few other things at play … but we could be here all day if we go into all of them!

much love ๐Ÿ˜˜ #tdil
