Brilliant :-)
Sure, it doesn't work as a lock anymore, but who can tell?
Actually, now that I think about it.. it does work as a lock. I mean, how often to people pull on a lock to see if it is really a lock? Plus, you can't forget your key.
You can actually assemble things inside a bottle using callipers and dividers, they generally have much better length on them than a pair of tweezers and are much easier to pick up than an adequate pair of forceps. I wouldn't doubt some of the narrow necked items could be assembled using forceps.
It's certainly not easy to do, but it is do able.
Any idea how these are done? It's very secretive on the site.
Whether that's actually what they do, I don't know.
Heat the glass till it's soft like taffy, and put the item in the bottle.
The put the bottle in a mold, and press the glass back into shape, and let it cool.
