Open helix structures in space contain liquids better than closed containers.

Instead of using coffee cups in space, dear spaceman, try drinking your coffee from corkscrew (helix) cups.

I have a hard time to see how somebody on Earth managed to find this solution to a problem in space, but it is very cool ! Potentially, it could also have big implications in nano workings, where things become so small that gravity is negligible and you need to devise alternate ways of containing fluids.
