Glow-in-the-dark-soap

 For bathing in the dark
  (+7)

Instead of having a bath by candlelight [which is a pain, because the candles always seem to either burn out or fall in], or just having a bath with the lights on [which is boring], use Glow-in-the-dark-soap! Incandescing in green or blue, this soap glows with a bright light, which will spread when added to water [so your bath also ends up glowing], and also make your skin glow till you wash it off. The more light you expose it to during the day, the brighter it glows at night.

       Nice idea so (+), but no explanation as to how it does this, or maybe it only works in Chernobyl?

       Without the "making your skin glow" part, it could work like the sun jar. (Solar cell charges battery.) The electronics would be embedded in transparent soap, and could be recyclable/reusable.   

       With the "making your skin glow" part, well, people do make soaps with glow-in-the-dark pigments (see links), but those aren't as bright or persistent as your description makes them out. You'll be able to see the bar of soap easily, but don't expect to find anything else by its light.   

       You can get around the weakness by installing a UV source in the bathroom and using any old fluorescent pigments. (Glow-in-the-dark also happens to be fluorescent.)

       A nice addition to glow in the dark bubble bath.   

       What I meant by the 'making your skin glow' was that the soap residue would make it glow until you wash it off, when it goes into the bathwater instead.
