The purpose of this instructable and the spirit in which it was written is to encourage readers to engage in a bit of experiential learning: to learn by doing.
This is done by showing a conceptual puzzle, and challenging the reader to duplicate it without directly spelling out how to do so.
I admit this is a fairly unorthodox instructable and it demands a lot from the reader, but I hope many people will appreciate the thought and effort that went into it.

I have a puzzle for you:
Can you put a full deck of cards into a completely unmodified glass bottle?
Obviously a wide-mouthed bottle provides no challenge . . . nor does using a tiny pack of cards.
The trick here is to take a standard boxed deck of playing cards and put the whole thing (box and cards) into a glass bottle whose mouth is far too small for such a thing.
Are you up for the challenge? Read on!
This is what people call an "impossible bottle," but in essence it's just a really cool one-time puzzle.
The complete object is a work of art similar to model ships in bottles.
Harry Eng is credited as the modern pioneer of the style, and there are several people that now practice the art form (a couple of good sites worth checking out: link, link). They make some amazing things, and I've become fascinated with the concept.
The idea is basic enough: Put objects into completely uncut, unmodified glass bottles, where the mouths of the bottles are seemingly too small for the stuff to fit in.
The completed bottles are visual puzzles / conversation pieces / art, that are simply intended to make observers think.
This instructable is here to get you to take the next logical step: do!
