So, why does metal have less oder. To smell it at all, you have to put it right near your nose. Why?
Is it: That molecules are heavier and therefore less likely to float around, rather than fall to the floor? Or that those little particles will stick more strongly (being metals) to each other and there are fewer floating around? Something else? All of it together?
I knew I should have taken more physics and chemistry. Except I hate them.
