Do you remember the device for cutting bottles with a wire that was heated electrically? My friends and I, collected a dozen Sprite bottles, and after lopping the tops at the shoulder, above the 'bumps', we polished the edges to be able to drink out of them without cutting our lips, and used those for our DnD gaming sessions.
