Puzzles are around us everyday. This simple bolt and dowel puzzle is part of a larger category of puzzles called impossible bottles. Impossible bottles are puzzles such as a deck of cards or ship in a bottle. There is often some work that is done before presenting the puzzle to others. These bolts and dowel will leave the observer scratching their head wondering how seemingly simple objects appear as they do.
If you would like to know how to make this very simple bolt and dowel impossible bottle, you will need a few items and a little time.
Since this type of puzzle is about the bottle just as much as it is about the bolts through the dowel, each puzzle will be different.
When planning your puzzle, keep in mind that the sum of the width of the dowel (5/8 inch for me) and the length of the bolt (3/4 inch for me) must be less than the width of the inside of the bottle. I selected my dowel based on the opening of the bottle then selected the bolts based on that decision. This is extremely similar to the bottle I used.
Before you proceed, I would encourage you to either mentally think how you would do this, or go out and do it yourself. What would you use? Water, magnets, toothbrush or floss?
Once you have thought about it - or if you just want to know how to stump your friends - read on for the process I used.
