sorry al, but that sounds too much like double talk to me.

any liquid under pressure has to over come the pressure before it can crystals (freeze). water may be purified or it might not, but it will still freeze, even if it has had all the impurities removed. underpressure the air molicules trapped in the liquid prevent the crystalization until it reaches the point that the gas gets trapped in the crystals. removing the gas allows the crystals to form immeadiately.

another point is that cold air is heavier therefore increases the presure on the water in the ice cube tray. bring it into the warm air drops the pressure. it also causes an immeadiate vaporization of some of the water, carrying off a part of the heat of the water. this aids in the freezing.

the more man learns, the more he realises, he really does not know anything.
