They also found that the force of surface tension of blood-like liquids is much greater in zero gravity, which surprised Kowalske. What? Why the surprise? EVE

They also found that the force of surface tension of blood-like liquids is much greater in zero gravity, which surprised Kowalske. What? Why the surprise? EVERY LIQUID will turn into spherical globules when not influenced by an external gravitational field and too small to form its own gravity. Why does he think the Earth is a sphere? Why do drops of water in the space station become globules? (Own gravity; Surface tension.)
