Plus pressurized pens are useful in more than just zero-g. I used to use one along with a waterproof note pad for note taking in the field. They're also not prohibitively expensive, although the ones from Fisher itself carry a pretty huge brand name markup, other companies sell them for a couple bucks each.
Wait....waterproof notepad?! How does a notepad hold the moisture from the pen? Or is this like a grease marker situation?
idk how it works but it does. I've been using Rite in the Rain for years but there are others too if you search it up.
Just guessing here but I imagine the ink doesn't contain any water, so an otherwise absorbent material that is treated with a hydrophobic coating would probably work for that.
the paper doesnt necessarily need to absorb the ink, the ink just needs to dry on the surface is such a way that it adheres well enough it doesn't rub off, or stay wet.
So really, you want a high adhesion, quick drying ink, which would basically let you write on any surface it'll stick to.
They're also great to bust open when scared, to make a quick getaway. Making zoidberg noises as you scuttle away is optional, but recommended.
