This process is called sublimation. Water or ice can also sublimate at temperatures below freezing. Because of the dry air in the freezer, ice cubes will sublimate and will disappear. If you store ice in your freezer for a long time, then the taste may be a little off. Boil your water, as others have said, to reduce the amount of bubbles.

Freeze the water very slowly. Either you can insulate your ice cube trays using a thermos or something similar, you can freeze them in a warmer environment than usual by altering your freezer settings. After every 6 hrs, the freezer make it on its heating coils to melt the frost that is present on the freezer coils.

When the temperature starts to increase above 32 F, or zero C, the timer of the freezer shuts off the heater automatically. In the meanwhile of this procedure, the hot air created by the heaters warms the air around the ice.

Thus it builds the top layer of frost hot enough to fastly sublimate, else to convert from ice to gas. The ice loses its volume or diminishes to a smaller size.

Always clean the mold out of the freezer before using it. Do not put food back into the freezer until the mold is completely removed.
