Cibi glass as used by Harrison Ford in Blade Runner. I wanted to display the glass with Johnnie Walker Black in it, but the whiskey has a pesky way of disappearing. (Evaporation. Yeah, that's the ticket! )
Fortunately, Japan has a long-established "plastic food replica" industry; practically every restaurant in the country has a display window filled with realistic models of the dishes they serve. A bit of negotiation and I was able to get my Cibi glass filled with urethane hooch. They did a much, much better job than I could have done on my own. I think they perfectly matched the color to the authentic JWB visible in the bottle behind the glass.
