Special Effects

[armoose]

I was wondering. Does anyone know how to simulate breathe fogging up a mirror. I want to do this practically. From what I know the science on fogging up a mirror has to do with the condensation of the warm breathe being approx 97 degrees in conjunction with water molecules that give the fogging effect. Does anyone know of a practical way of doing this without me having to stand there and breathe on the glass outside the frame?
Thanks
