Coffee cups used in the briefing room (TOS)

I think it's pretty well accepted that they were Styrofoam. The raised markings on the bottom are not something you'd see with a paper cup.

I always figured they were painted Styrofoam. They even sound like it when someone puts one down or grabs it out of the air (like Kirk did in WNMHGB).
 
And paint that wouldn’t dissolve the cup had lead in it then? Stupid me tried to spray paint a styrofoam creation I fashioned as a child…worked great for ST III..

Lead was in oil based paint up till the late 70s. It isn't the reason the cup would dissolve-it's the solvents in oil paint (paint thinner) that will break down Styrofoam
 
Light coats of solvent spray paint could have been sprayed on carefully allowing the first to dry over night before spraying the second one (I have been painting and refinishing for 39 years now)
 
Also, please consolidate your posts into one next time, instead of four in a row.
Thanks

supposedly you can paint Styrofoam with acrylic. I'm about to test that this week on a couple of rc plane designs ive been working on with polystyrene, so I am curious about it, myself.

It is interesting the degree of effort they went to just for some blue cups with the black stripe. Its easy to forget, even the smallest props are sometimes a labor of love.

Except for the deadly spray bottle on Conscience of the King. That was just lame :D

:rofl: Im going to order some of these 6 ounce cups-$1.95 and spray two coats of silver then take a sharpie on the ring and try to post it without getting chastised
 
I suppose I should know this…but….

I seem to recall that there was a web site dedicate to all the props; explaining their background , origins, etc. Does it still exist? And, should the styrofoam cup be added ?

Not quite deadly; McCoy was able to save Riley. But yes, a recognizable plastic spray bottle (albeit of a type not generally found in consumer products back then) does seem like an odd container for a lubricant, especially a highly toxic one.

And as to posting more than twice (or even more than once) in a row, TrekBBS does allow you to edit your posts to expand them, many hours weeks after the initial post (much longer than, say, Fountain Pen Network [whose editing-allowed interval is itself much longer than it used to be]). It's not like LaughingPlace, where the interval when editing is permitted is, ahem, "laughably" short.

The same kind of spray bottle (maybe even the exact same prop) is also seen in sick bay in Space Seed. That type of plastic spray bottle with the trigger/nozzle top was fairly new-ish at the time. It had just been invented at the beginning of the decade, when improvements in materials manufacturing made it possible to make a plastic bottle and spray mechanism like that, which was durable enough for repeat use instead of being brittle and easily broken. Before that, stuff like household cleaners came in aerosol spray cans, or glass bottles with a pump spray mechanism.

Wikipedia says these plastic bottles became popular in the late 1960s, but doesn't give a source on that. So maybe it was still the sort of thing you typically wouldn't see every day. But still, it would have helped if the prop masters had at least given it a coat of grayish-silver paint to make it look a little more futuristic.
