I have hesitated for a while whether to share this cheap cheat bit here or not, because if you have ever dealt seriously with the subject of “impossible bottles” and its masters like Harry Eng, you will know that it’s an absolute no-go and a disgrace to temper with the bottle you are trying to stuff stuff into in any way!
Yet it is understandable that not everybody with just a passing interest in this matter has the means or know-how, not to mention the patience, to master this craft and art. (I have actually tried it, and it is both an arduous and satisfying experience. You can read a bit more about it here.)
So for those easy come, easy go folks among you, let me tell you that there’s a fake “bottle” out there (it’s not even made of glass) that you can easily fill with the biggest and most complex objects, which should make for a nice display on any shelf. This bottle I came across is produced by Peleg Design (they also produce other magic-themed paraphernalia), and its shabby secret is not actually designed to be hidden well:
Let’s consider this as a beginner’s ticket into the wonderful world of impossible bottles. But please do not trick yourself into believing that you have accomplished anything magical by filling and displaying this kind of bottle!
