How to get last drop of ketchup out of the bottle.

Yeah, the "official" story was half pom...'capt for a "mad aunty" who reckoned that there were Cornish Pirates in part of the family.

Relos have been doing the genealogy, and discovered the cornish part, but declared them tin miners.

No wonder I liked the pasties.

The term thixotropic also applies to the ink in Fisher Space Pens; that's where I first saw the word. These are the pressurized ball-point writing pens created for NASA astronauts in the 1960s and still available from a variety of sources. The ink flows when the ball point is under pressure, and the pressurized reservoir combined with the special ink enables the pen to write properly in microgravity ("zero gravity" as some erroneously say). On Earth these pens write perfectly well with the point up, as when you are writing on a piece of paper held on the wall at face level as most would naturally do.

Years later PaperMate introduced the EraserMate, a pen with erasable ink, which also used a pressurized reservoir. The ink seemed similar to that of the Fisher pen, though with the added property of being erasable for a few days after writing, so I assume it is thixotropic too.
 
I've reached a point in life where I'm successful enough to not HAVE to get every last molecule of ketchup out of the bottle. Proper planning has another bottle in waiting.

But, the Scot in me still flings the bottle with a quick wrist snap (or two) to get the mustard/ketchup/etc to the pouring end of the bottle.

Any more than that and it becomes somebody else's job.
 
Well, presumably in some instances you desire a permanent ink even in spaceflight. Pencils were indeed the Soviet/Russian approach for a while, and I even read a Russian cosmonaut's comment poking fun of NASA's expensive pens when his country was content to use cheaper pencils—but it is well known that the Soviets bought a large number of Fishers soon after they became available.
 
If anybody wants to rent my Space Pens, let me know. The RKA is welcome, too.
