Most museums ask that you don’t touch things. A few have items that it’s okay to examine. The Pen Museum has one that you actually use. You’ll need to be shown how but then you can use the same tools that pen manufacturing staff did.
They had to make hundreds and you’ll only need to make one before you stop for a rest so it’s not as if we’re putting you to work or recreating the pressure that staff used to have. But it is about pressure in a literal way: you’ll see just how hard it is to make a pen nib.
You’ll come away from this one exhibit understanding how it works. You’ll really appreciate the mix of artistry and sheer effort. And you will never look at a fountain pen the same away again.
