Harry Eng the Master Bottle Filler

The Puzzle Museum:

Our venerable curator has gone nearly blind with a magnifying glass but has failed to find any sign of breaks or glue in this plank. It is a One Gallon Bottle and the plank measures about 14 cm x 12.5 cm x 1.8 cm thick.

Even if one could use the key that is loose in the bottom of the bottle, the padlock on the bottom of the plank is too large to fit through the neck of the bottle.

The plank is engraved with Harry's "Think" Logo.
