Consider a solid sphere (capable of withstanding full vacuum) of 3m diameter filled completely with water resting at sea level. It has a 10cm hole at the bottom with a cork on it. If you open the cork, what is the time taken for water to completely drain out.

What happens for higher diameter spheres?

(In reply to re: solution (maybe) by Alexis)

Viscosity explains the ketchup, but surface tension will not retain the contents.  And we can assume a vortex concept so that equally volumes of air and water are exchanged, well, on average anyway?
