Second, will you rely on mother nature or on refrigeration coils to freeze the water?
People often ask me what to wear in order to be comfortable riding a bicycle in temperatures that could freeze boiling water before it hit the ground.
Or, put your credit cards in a tin can fill it with water and freeze it.
NASA's scientists have designed a device that would be carefully sterilised, and would then melt its way down through the ice, allowing the melt-water to freeze behind it to prevent contamination.
Water on the tiles could freeze as the shuttle reaches orbit, and could cause the tiles to come off.
Once frozen, the material was placed in a freeze-dryer that removed all the water from it over the course of four days.
ECONOMIST: An old idea may help solve the problem of plastic waste
Paul Holland of the British Antarctic Survey (BAS) stuck to his findings last year that a shift in winds linked to climate change was blowing ice away from the coast, allowing exposed water in some areas to freeze and make yet more ice.
Siberia gets so cold that boiling water poured from a pot can freeze before it hits the ground.
As described by ice sculptor Joseph Amendola in his book Ice Carving Made Easy, written records dating back to 600 BC reveal that in the highlands of northwest China, farmers would flood their fields with water, wait for it to freeze, harvest blocks of ice and then store them in insulated facilities to help preserve perishables like seafood.
The habitable zone is the region of a planetary system which is neither too hot nor too cold - such that water on the surface of a planet will neither evaporate nor freeze, but instead can stay liquid.

The reason for the excitement is that, although the existence of ice on Mars has been known since 1666, when the planet's polar caps were first seen, the low temperatures and air pressure there mean that water, even if heavily salted, is likely either to freeze or to evaporate.
The books were then freeze-dried, a process that evaporates the ice into gas to stop further water damage or mildew.
The regulator - the Water Industry Commission for Scotland - said it was likely to extend the price freeze for another year.
We ate freeze-dried packaged food and had a mix that became an orange-grapefruit drink when water was added.
They said water seemed to have flowed down two gullies in the past few years, even though liquid water cannot remain long on the planet's frigid, nearly airless surface because it would rapidly freeze or evaporate.
