Frozen perfection

[sawyl]

It seems as though ice is no longer ice. If it isn't double frozen, it isn't worth touching. Seriously, how is double freezing supposed to help? I mean sure if you drop the temperature down to just below the melting point, keep the crystals and chuck the liquid, you're going to have purer water when the stuff melts, but the mere act of freezing twice isn't going to help.
