Question:

How do people get a big object into a beer bottle?

I've seen shells and toy ships in beer bottles that shouldn't fit in there so my question is, how do they do it?

If your hands shake, forget about trying it yourself!
When I was a kid I thought that they made the model first, and then they would somehow put the bottle around it!
Those artists (I had the chance to watch one of them at work) are very patient, and very careful. They use very delicate 'tools' (anything long and thin can become a tool for them) and plan carefully every move, specially when they handle glue because every mistake is fatal in such an art.
