I am a lab researcher. We work on particles containing anti-tuberculosis drugs, meant for inhalation by patients whose lungs are infected. Our lab's particles are not 'nano'-particles as the current fashion dictates, and a potential collaborator recently made a (good-natured) joke about how the size of our particles reminds him of flying elephants. If you permit, I'd like to answer him with scientific rationale as well as your poetic image,  modified as attached.

This is the great email I got today.
