In practice its going to be more complicated and the difference is probably pretty slim, cool though.</p>TerminusMon, 16 Feb 2009 09:55:32 -0000http://www.ohgizmo.com/2008/05/09/ice-mold-creates-perfect-spheres-of-ice/#comment-1766918<p>How exactly does the shape of the ice prevent it from melting? I call BS.</p>samFri, 09 May 2008 11:23:14 -0000
