Who the hell thinks a siphon works because the air is pushing the liquid down? It would make the liquid spill out of any container, even without a siphon!
It's a very common Freshman chemistry problem to ask if a drinking straw will work on the moon.
It won't; atmospheric pressure is an important feature in the working of drinking straws. You also can't make a drinking straw longer than about 3 stories high and use it with your mouth, not matter how hard you suck on it, even if you're a Freshman cheerleader and have perfect sucking skills (sure you could build a mechanical pump but that's a different thing.).
This is why people thought siphons work the same way, I figure.
I always thought of barometers, same difference I suppose.
And "ionic liquid" is a very interesting wikipedia article, for those of us who didn't take college chemistry but kinda wondered about the vapor pressure of salt.
