This puzzle is my craft. I made this puzzle for a Coca-Cola bottle. The bottle is the imitation of the first Coca-Cola bottle (1899) produced for 125. anniversary of the company. This puzzle is inspired from well known wine glass puzzles. The aim of this puzzle is solving the disentanglement puzzle at the left, taking the key and opening the padlock at the right. This is a very easy mechanical puzzle to solve. But I made it as a decorative coffee table puzzle for my bottle. I used two kind of wood. The base is white pine, and other parts are a kind of beech. Finally I made an oil finish.
This puzzle is different. The upper dowel is fixed and on the middle part there is a slot. For
removing the bottle you must shift the middle part, but you can’t remove it completely from the assembly. If you want make your own bottle safe puzzle I prepared a file that contains detailed instructions, dimensions, drawings photos etc. You can download or preview this free PDF file from here (1.2 MB on secure server box.com)
