This is a puzzle bottle with a long natural colored wooden shaft going from the neck to near the bottom of the bottle but does not touch the bottom. "Impossibly" going through the shaft at a 45 degree angle is a metal screw. Inside the bottle are three metal washers. The object of the puzzle is to find a way to get all three washers to hoop around the screw. The bottle is sealed with a wooden stopper and the bottle is very old with bubble in areas of the glass.
