It would probably not be too long before the greenhouse disintegrated. -- Jeff (cut "thetape" to reply) |

This is interesting, and gives the kids something to do, but it's only delaying the inevitable. In fact it can be argued that it's an environmental disbenefit rather than benefit, since the bottles used in this way can no longer be recycled, or so I'm told. Steve |

Steve I line my GH with plastic bubble wrap, and that lasts several years before disintegrating. I'd imagine the bottles would last longer, being thicker.... Jenny |

Polythene = polyethylene. So how different? - can you point me to an url with the chemical structure of both? (Not doubting you, just curious). -- Kay |

Polythene (polyethylene) is an addition polymer of ethylene i.e. (C2H4)n PET (polyethylene terephthalate) is a condensation copolymer of terephthalic acid and ethylene glycol, i.e. (COO.C6H6.COO.C2H4)n http://en.wikipedia.org/wiki/Polythene http://en.wikipedia.org/wiki/Polyethylene_terephthalate -- Stewart Robert Hinsley |

Sacha says...
The water here is so chlorinated that we have a filter on the kitchen water tap and take bottled water to the bedrooms. The tap water here is drinkable most of the time. Occasionally it is over chlorinated - very noticeable after a sip of tea which tastes metallic. It also goes brown sometimes for a day or two for reasons unknown - possibly someone working on the mains. We keep some bottles of spring water for such occasions. -- David in Normandy |

Our milkman brings us bottles of water three times a week, only because the taste of chlorine is unacceptable to us. I insist that the kettle is filled only from the filter tap and I know, always, if someone hasn't done that. -- Sacha http://www.hillhousenursery.co.uk South Devon (remove weeds from address) 'We do not inherit the earth from our ancestors, we borrow it from our children.' |
