Very cool. There has to be a downside... doesn't there?
I'm very skeptical. I think it's a hoax.
I've had bleach and water mixed in plastic bottles and left outside, and it never glowed.
I'd like to watch the video, but I can't see it on either one of the computers at my desk.
It's in Italian. And the "bulbs" seem permanently installed, shoved halfway through the ceiling--so in theory the top is sticking out of the roof to gather the sunlight? But if it's sticking out like that, it would seem to be just a tiny skylight.
Why don't swimming pools glow in the dark, then?
I'm guessing they are little skylights and the water acts as a lens of sorts to bring more light in. The clorox is probably to keep the water clear and oh so funk-free.
However I can attest to the warm and romantic glow thrown off by a pickle light, however brief.
