Eating high tea with chopsticks
Water is polarised. So polarised, in fact, that you can eat it with chopsticks.
By polarised I mean, of course, that the water molecule is highly polarised – it behaves like a magnet with a positive and negative side. It has the highest internal cohesion of the non-metalic fluids, a fact that gives rise to 115 m-high redwoods and Jesus bugs striding across ponds.
Chris Webster, a meteorologist over at the MetService Blog, waxes fondly on the wonders of surface tension in water, which reminded me of a favourite demonstration in microgravity.
In space, no-one can hear you scream gravity is so weak, it loses out to surface tension, so that water easily beads together and you can eat it with chopsticks.
