How do you prevent air bubbles from forming in ice cubes in the freezer?

Boil the water and allow to cool before freezing.

This drives out the dissolved air.

In principle, it is possible; in practice, it isn't worth the bother. Water contains a certain amount of dissolved air, which will come out of solution as water freezes. If you outgas the water by placing it under a partial vacuum (until the water boils), much of the air can be removed.

Hot water has most of the air out of it already, so has a better chance of producing cubes with no bubbles.

The trick is to boil the water and then freeze it straight away.

Boiling helps diffuse the dissolved gases out of water.

Placing thw water immediately in the freezer will help prevent these gases dissolving inti the water.

If you can keep the water moving slightly while it is freezing it will be completely free of bubbles and be crystal clear. I don't know how you would do that though.

nope. just use hot water . cold water hads too much oxgyen. i thank...
