Hi all, For a science project, I'm using mist, created by an ultrasonic humidifier. An ultrasonic humidifier uses a membrane that vibrates at ultrasonic frequency to disperse water into tiny droplets, resulting in a cool mist. Now I was wondering; is there a way to reduce the droplet size by adding something to the water? I really don't know much about chemistry but I would guess the droplet size depends on the viscosity or maybe the surface tension of the fluid? ps. The mist can be contained, and does not necessarily have to be used in an open room, so no health risks here. Tnx a lot!
