comment How do whisky stones keep your drink cold?
What about thin plastic spheres with water inside? Theoretically this allows the water to change phase without watering the drink, at the cost of reduced surface contact. Would that be more or less effective than the methods mentioned?

comment 3D movie glasses making white light look red and blue
"Dolby 3D glasses are more expensive and fragile [...] and are not considered disposable." This rings a bell, the glasses even had RFID tags to prevent theft. Interesting to know it has nothing to do with polarization.

comment 3D movie glasses making white light look red and blue
I noticed the effect on all lamps along the walls, and I think even the tiny lights on the ground that help you find your seat (those were too small and the effect on them too subtle). Nothing else looked that way, only the light sources, obviously excluding the screen. I didn't think of looking at my phone to compare.

comment Does a byte of data weigh anything?
The weight of "a byte of data" depends on the encoding. I can encode a number as stones in a bucket and this would have a different weight than the same number in a hard drive. Not sure if this makes the question different enough.
