I found my original post in Ungarbage - Recycling:
You know you're a "reuse everything" person ... when the guy who runs the recycling depot saves water cooler jugs for you, because he knows you will grab a fine-tooth hand saw and turn them into:
- water scoops, storage bins, emergency snow shovels (remove top)
- wasp traps (cut off top and invert)
- garden cloches (cut off bottom)
- microclimate greenhouses (cut off top and bottom to form a sleeve -- peppers and tomatoes love them)
- mud for robins building nests (sink the bottoms you cut off to ground level, add mud/cob/clay and keep moist)
Also:
- I saw a guy at a street performer festival use one as a drum, along with other found objects. He was really good!
- For mouse resistant storage, cut off top and invert with the cap on
With the older #7 plastic water jugs, cutting them is a bit of a chore. I have yet to find a power saw that will cut them without cracking. I use a wood saw or hacksaw and it works fine, it just takes time. Once they are cut and the rough edges smoothed off with a rasp or file, they are remarkably durable. I think some of the new jugs are #1 PET.
