  1. Gather the materials

    You will need a quart sized plastic freezer bag, 70 percent rubbing alcohol, water and a measuring cup. Use two plastic bags to ensure no leakage.

  2. Measure the water

    Measure out two cups of water, and pour into the freezer bag.

  3. Measure the rubbing alcohol

    Measure out one cup of 70 percent rubbing alcohol, and pour into the same freezer bag.

  4. Mix the contents

    Hold the bag upright on a flat surface, squeeze out any excess air and seal it. Hold the bag in both of your hands, and shake it to ensure the ingredients have mixed properly.

  5. Freeze the bag

    Place the bag flat on its side in the freezer for a minimum of four hours. Remove any remaining excess air by opening the bag and rolling the frozen mix around, then squeezing the air out again. Place back in the freezer until the gel ice pack is needed.
