Luminous Foot Coating

For people with partners who can't sleep with a light on.

If, like me, you sleep with a partner who wakes up or gets grumpy whenever you put a light on, then this could be the solution.

A paint-on luminous coating for the feet (though it may be entertainingly applied elsewhere) which would light the way to the bathroom during the night and which allowed you to read under the covers while your partner slumbers in peace.

Should be available in many colours, but I picture a nice green glow.

       Peter: They may, however, give off an annoying glow all night (unless you wear them to bed).

       Remember, folks: "Glow in the dark stuff" only glows for about five minutes after the lights go out, and even then it's incredibly dim -- barely bright enough to see at night, nowhere near bright enough to illuminate anything else.   

       Consider that the next time you suggest "glow in the dark foo".   

       (Unless we're talking about electroluminescence, but that's not something you can just paint on, and it needs a battery anyway; or radioactive phosphorescence, and I don't think you want to paint your feet with radium.)

       Tritium works too. A bit of tritium gas in something coated with phosphor will glow for a lifetime...

       (actually, StarChaser, tritium has a halflife of only twelve years or so. It's used for some emergency-exit signs, IIRC, and it does have to be replaced periodically.)   

       Egnor: the obvious solution is to have small ultraviolet lights on the baseboards. These would cause the glow-in-the-dark paint on your feet to fluoresce, allowing you to walk to the bathroom. Coverage wouldn't have to be as complete as for normal lights, since your feet would be "charged up" and continue to glow in between walking through UV-illuminated areas. The lights could be the old discharge-tube type, or new ultraviolet LEDs.

       Also, you'd get a nice tan on your feet.

       Wiml: Well, their hype said 'a lifetime'...Bad tyger! Beliving what you read...<grin> I guess they meant a rave kid's rave lifetime...

       Genetically engineered phosphorescent athlete's foot?

       Mephista: Because then it wouldn't be half-baked.

       Look; forget all the paints and batteries. Just leave all the lights on and blindfold your partner.
