For several years I was dropping pennies from my pocket change into a large 5-gallon glass jug. After awhile it got so dang heavy I stopped but am stuck with this heavy thing. I can barely pick it up now. I am worried it will shatter in my hands one day as I move it or something smacks into it. Trying to shake the pennies out doesn't work - the pennies quickly clog up the opening. I'd like to get them out and cash them in, but do so without resorting to smashing the jar and separating the glass shards from the pennies. Any ideas? One thought is to try a basic glass cutter and try to cut the top off. Thought I'd ask here first.
