1. Germs can be spread by a sneeze. First there's a big bunch of germs expelled. Then they gradually diffuse to fill the room.
2. When someone passes silent gas, one can smell it because the gas diffuses throughout the elevator.

Putting on a perfume.
Why everybody has questions about diffusion? It is really not that hard to understand of concept!

I think that a great example would be a fart, the gas diffuses until its not concentrated and you can't smell it. Is that good enough?
