Corkscrew Cups Could Keep Space Drinks Flowing

holy_calamity writes "A Canadian chemical engineer has a novel solution to containing liquids in space. He has been experimenting with corkscrews of ribbon-like material that keep liquids suspended in their center while in microgravity. This effect is caused by the surface tension of the liquids. The helical containers allow the fluid to be sucked out of the coil in one go. In more conventional shapes, such as coffee cups, interaction between the container and the liquid's internal pressure makes the beverage break into annoying globules you have to chase with a straw."

  1. I'm interested in how they simulated microgravity by kcbanner · · Score: 3, Interesting

    They tested the candidates in a tank that simulates microgravity using two different liquids of equal density. I wonder if the surface tension of those two liquids affects the experiment at all? Thats interesting.

    That depends on your outlook, now doesn't it ?

    Who owns english ? Who has the power to authoratively say what is correct english and what is not ?

    In Germany it's simple, most people don't question authority, so everyone accepts that whatever Duden chooses to put in its dictionaries is correct, everything else is wrong. Yes, even if 99% of the population, including linguistically trained people, do it differently.

    You get strange things like; "Everyone says gukken, but it's really kukken that is correct" (for look, glance). If you try asking a Germany -WHY- gukken is wrong if that is what everyone says, you get a bland stare, they don't really even get the question.

    English, and most languages really, are somewhat more open: The *natives* define the language. Those putting out dictionaries merely *document* the language. Yes, there are "common misperceptions", i.e. things that many people do but which are nevertheless wrong and should probably remain so. Those are the things that break the -structure- of the language.

    But stuff like meaning of phrases and/or pronounciation changes meaning over time trough actual use. Also, the same phrase has different (often related, but different) meaning in different fields. A photographer and a filesystem-designer do NOT mean the same thing when both talk about "taking a snapshot".

    Begging the question means one thing in formal logic. In practice, it has other common meanings in everyday english. Deal with it.
