I was talking to a friend the other day and they were telling me about some smoke chamber device. Apparently a 10 gallon chamber can be filled with smoke and some kind of "ray" would pass through the chamber and carve out a path in the smoke.
Does anyone know anything about this? Do you know what kind of ray my friend was talking about? Does this smoke chamber device have a name?
