What a beauty!
Now... if it was possible to use whole bottles filled with water then it would get warm
during the day and stay warmish all night. (maybe) Grow warm weather plants in winter. Hmmm.... any clues anyone?

 What a brilliant idea for a greenhouse. Its probably not practical for the likes of us, it would mean drinking an awfull lot of fizzy pop. But at a school it would work a treat, just get the kids to bring in there used pop botttles & 300+ would be there before you new it.

somebody near here simply put a wanted post on our freecycle and left a bin outside their house for the bottles to be dropped into, think they got their amount needed pretty quickly
