Folding the Ice Sheet if necessary, immerse it in the water.  

Note: Warm water will help speed the hydration process.

Place a plastic bag between Ice Sheets if stacking.  Do not stack too many directly on top of each other as this will affect freezing time (and risk an ice berg!).

Fill sink to level which will allow the Ice Sheet to be fully immersed in water.

Holding the Ice Sheet under the water initially will help start the hydration process.

The cells will inflate over a period

of five to ten minutes.  The water is absorbed by crystals in each cell, creating a gel.

You can check the progress of hydration by feeling the cells.  

They will become firm and bulky.

When the Ice Sheet is fully hydrated, remove it from the water and repeat the process for as many sheets as required.

If your freezer compartments are small then fold the sheet in half, ensuring that the foil sides are touching (material side out).
