How does this not heat up? Wouldn't the bottle swell and eventually rupture? Don't think this would last long in the Florida sun, really rough on plastic.

I missing something, Why the bleach?

malka1 (author)LordMekk2011-11-06

also the bleach helps to make a wither light

Bleach helps prevent growth of algae in the closed bottle. This idea has been around for a while, it was posted almost a month ago here and it was in the news way before then. But it is a great idea and so simple to do.
