Homemade Frozen Blue Ice

Homemade blue ice is used in reusable ice packs. Instead of buying expensive ice packs from the store, making your own with ingredients you have on hand is a cost-effective solution. You can add blue food coloring for the traditional ice pack look or any color you desire. The blue ice packs are still soft when frozen, giving them a unique pliability and allowing them to conform to your body part.

• Medium glass bowl with a spout
• Water
• Isopropyl alcohol (rubbing alcohol)

Instructions

• 1

  Mix 3 cups of water with 1 cup of rubbing alcohol in a glass bowl with a spout.

• 2

  Add 2 to 3 drops of liquid food coloring. Stir the mixture to combine.

• 3

  Hold open one gallon-size plastic bag and slowly pour in the mixture. You can also make two quart-size packs. Partially seal the bag and then compress slowly to remove the air. Be careful to not allow any of the liquid to leak. Place the pack inside a second bag to prevent leaks. Remove the air from the second bag by compressing the bag gently.

  Lay the bag flat in the freezer; allow at least 2 hours for the pack to get cold.
