Ultrasonic atomiser + Glass Dome = Weather?

I saw this project on hackaday recently, http://hackaday.com/2012/11/15/an-extemely-unique-weather-display/ Its very cool, and got me thinking.. if I used a ultrasonic atomizer type thing, I could easily show fog in a glass dome.. and perhaps if I made enough fog it would condense on the top of the jar to create rain.

Any thoughts on whether this would actually work?


NB, I moved this from Science and Measurement as it seemed this was a better board for it
