Whenever someone comes back from a walk outside on a crisp day, they have an odor that’s distinctive of outside. My nose is not the best, but I’d say somewhat metallic. What is causing that smell?
In: Chemistry
You know what is kind of interesting? Metal has no smell. It’s very stable and doesn’t emit anything for our noses to detect. What we think of as the smell of metal is actually usually our body oils, that have rubbed onto the metal, oxidizing.
If the smell of someone walking into your house smells sort of metallic it may not be the smell of the outside, but of a burst of their body oils greeting your nose, which you probably get used to quickly as they shuffle around inside.
Maybe not though! Just a thought.
