    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.

    this is used in very hot places, but if you are concerne you can use non retornable bottles that are heavyer

    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.
