Correction: 6:33 Dipole moments are typically represented going positive to negative, rather than negative to positive.
There are somewhere between 20 and 74,963 kinds of ice. Water can do all kinds of weird stuff when it freezes. So far scientists have experimentally shown crystal structures for 19 kinds of ice. Or maybe 20, depending on who you ask. We’re going to charge through as many as we can in ten minutes or so.
