This is just the best analogy for this type of thing. Absolutely perfect, a masterpiece in my opinion.

The illustrations you created to highlight exactly how tiny aerosol particles can be are really insightful, and I think they add a great layer of understanding to the article. Even though I regularly work in micrometers, even I needed a reminder of just how small they really are. Just know that the extra effort you put in to create those illustrations are very much appreciated!
