This is my first bottle puzzle. It is simply called Bottle 4 and was manufactured by a Belgium puzzle company called Eureka. Wil Strijbos designed the puzzle. The goal of this puzzle is to remove the metal ring from the bottle. Puzzle Master rates this puzzle an 8 out of 10 as far as difficulty. Getting the ring out was not that difficult but putting the ring back took a little longer. There is a way to get the ring out without following the proper solution method. This puzzle is a cool addition to my puzzle collection and I look forward to collecting more of these bottle puzzles. You can find this puzzle at Puzzle Master and the solution can be found here.
