I agree with EvanHarper. Its like the water molecules almost have friction against each other, keeping them formed togeather into a sphere. Well, at least i think so, learned it in Biology class a few weeks ago.

lol Obviously.

surface tension pulls it into a sphere same as raindrops and bubbles

Which is why water heated in a container to a temperature where it has a much higher vapor pressure, will show less surface tension? The surface tension is the result of the difference between the liquid's would-be vapor pressure and the pressure of the gas surrounding it?

I wish I could believe that the people talking about gravity here are just trolling, but you might actually believe it. Idiots. The acceleration due to gravity at that sphere's surface would be about 1.8 x 10^-8 m/s^2, ie, vanishingly negligible. Gravity has no relevance at this scale. The sphere is held together by surface tension; polar water molecules are attracted to other water molecules much more strongly than to nonpolar nitrogen and oxygen molecules. Obviously.

everything has gravity, so the waters gravity attracts it to itself, forming a circle, explaining circular planets

is that what they do in space all day.. play with water erm well.... I just think it was worth it........ maybe Ill get a jaquize (sorry forgot how to spell it............ doh!

yeah thats why planets are round...

Water is atomically attracted to itself. A sphere of water in micro gravity is logical.

their in space
