Ever wonder why libraries and used book stores smell so good?
Wonder no more! Andy Brunning, a chemistry teacher from the UK, has created an infographic — shown below — that breaks down (ba-dum-chik) the chemical reactions that occur in paper and ink as they age, causing the “old book smell.”
Next time you thumb through the pages of an old book, taking in its intoxicating aroma, remember what’s behind that comfy smell: science!
For more explanation of the science behind the old book smell, check out Andy’s blog Compound Interest.
