made using boiled water were more likely to break in halves when i tried to
get them out from the plastic mold. The ones that were made from tap water
were, oddly, mostly intact. Is this because the boiling process introduced
some factors that prevented the ice becoming perfect crystals? But this is
counterintuitive ahh,, given that distillation purifies water.. |
