Bmandk Posted May 26, 2012 Share Posted May 26, 2012 Lately I've been thinking: Sand doesn't stick together when it's dry. Water doesn't stick together either. But together they stick together. WTF? Link to comment Share on other sites More sharing options...
miniboxer Posted May 26, 2012 Share Posted May 26, 2012 water does stick together, just not in a visible way. It is called cohesion, and it is why water always beads up when spread out on glass. Without it, water would just spread outwards until it was only an atom thick. Link to comment Share on other sites More sharing options...
TheGuy Posted May 28, 2012 Share Posted May 28, 2012 It can't be an atom thick, it's a particle (H2O, anyone?). It can only be a particle thick. :) Link to comment Share on other sites More sharing options...
Bmandk Posted May 28, 2012 Author Share Posted May 28, 2012 And a particle is relative since it has different sizes. Link to comment Share on other sites More sharing options...
