Fisher space pen cartridge

[Waterman]

Hi I was wondering since they say their cartridges are pressurized by 35 psi wouldn't that cause somekind of danger if someone were to...........oh let say BREAK IT!? Wouldn't the sliding float ball just shoot out including the ink?

I've never broken one, but there is relatively little actual gas under that pressure. I bet it'd make a mess..

hmmm maybe I'll try it out and post what happened.

According to Fisher's site:

 

The new visco-elastic, thixotropic ink, with a consistency similar to that of very thick rubber cement, flows as a result of the shearing action of the rolling ball in its socket. This shearing action liquefies the solid gel thixotropic ink, allowing the pen to write smoothly and dependably on the most surfaces and even underwater.

So I'm thinking that it's unlikely that the ink would "shoot out".

My apologies for being somewhat off-topic, but I've been waiting for an opportunity to ask this question: what's the deal with the Fisher space pen? Not technologically, but what does it feel like to write with it?

 

Perhaps it's just the potentially biased opinion I have about ballpoint pens- that is, they're all bad. Rollerball pens are another story, but I don't think I've ever used a ballpoint pen that didn't blow. Does it write like a ballpoint, but a bit more consistent and steady, or more like a thick rollerball?

Actually, they write pretty well. Not as smooth as a fp but better than your average bp. I ALWAYS prefer to use a fp, but a space pen works everywhere, writes on almost everything and is extremely reliable. I carry a bullet pen with me everywhere. My only complaint is that the ink will build up on the tip sometimes creating a smearable blob.

I wasn't using fps when my space pen grew legs, so I can't compare, but I rather liked mine. Was smoother than the disposable bps usually floating around and it really did write on anything, anytime. The occasional ink blob but it could be wiped off easily.

I have a black bullet pen that I carry everywhere, along with a sheet of graph paper, folded ala pocketmod. For quick jotting the pocketmod and space pen come out together and I'm good to go.
