Dreamworks released cans of it (it was actually air freshener, of course) as promotional material back during the initial release of the film... they were floating around for a while on eBay. I'm sure One of those cans would be great source material for a screen-accurate version
The spray can itself appears to be a bit weird. Seldom do I recall seeing a can with a metal bottom rim and a plastic style sprayer. plastic sprayer looks other than normal as well. I haven't explored sprayer emitter but this design just doesn't seem to register with me.
Ha. "emitter" I can see a lightsaber addict doing a search now and going Poo. WTF?
Actually, I'm "'da woman," but I'll take compliments where I can get 'em. I don't think this is completely accurate, so I want to wait for the world to weigh-in before I post it on the Free Props thread -- I felt like the space shuttle label discussion went on too long over there.
