I need an idea on how to immediately "frost" a window with the wave of a hand, etc. I need to be able to write on it, like you might do on a car window in the wintertime.

Any ideas will be appreciated.

Thanks,

There are several ways I can think of off the top of my head to do it. Of course, a lot depends on the nature of what you're doing. Will this be an existing window (I.E. of a house, store, etc), or a prop window used on stage?

It will be a prop window - a preliminary effect to another routine. I have thought of using carbon dioxide, but I can't figure out a way to control it without having some sort of nozzle in my hand. I also thought about steam, but the steam rising wouldn't be the effect I'm looking for. I also thought of double-pane glass with the "frost" in the center. Easy to control, but how do you write on it?

Greetings...

If the window were sprayed from behind with a cold liquid, and there was enough moisture in the air of the performance location, would that cause the front of the glass to "fog"?

I'm thinking like when you hold a can of "dusting spray" upside down and refrigerant comes out...

First thing that came to mind was to use baby powder in a way that would leave a light dusting on the glass to appear fogged.

There is a glass that is "Frosted" and turns clear when electricity is run through it. When the juice (Power) is turned off the glass would fog or frost up immediatly. The problem then would be how to look like you are writing on the surface. Do you have to use your finger or can you use a pen or other device?
