I save all my cans that need a can opener, spinach, soup, tuna, peaches, etc. there are lots of uses for them. for example, holding nails, screws, small parts, anything else that might need a container. for glue and paint and cleaners anything that comes in a big jug and I need to apply it with a brush. pop some holes in the bottom add soil and they make a perfect small pot for starting seeds. put them on the exhaust stack on tractors to keep out the weather. there are lots of uses for tin cans.
I never throw cans away
