Introduction: How to Make a Gel Ice Pack
Have you ever got injured, and prefered not to a bag of peas of piece of uncooked meat to soothe your pain? Fear no more, this instructable for creating a gel ice pack at home will solve all of your problems!
You will need:
2 Ziploc Freezer Bags
Disclaimer: Rubbing Alcohol can be dangerous if consumed in large quantities, and can cause irritation to your eyes. Infants and toddlers can pull a bag over their heads and suffocate when they are unable to get them off. Take careful caution when creating your ice pack, and keep the supplies away from children.
Also, I have found that Ziploc bags work best for the ice pack, sometimes the generic brands are not as strong.
Step 1: Add Water and Rubbing Alcohol
Fill the plastic freezer bag with one cup of rubbing alcohol and 2 cups of water. For a less dense gel, reduce the amount of water to 1 cup.
Step 2: Remove Air
Try to get as much air out of the freezer bag before sealing it shut, then put it inside a second freezer bag – this way there is less chance of a leak.
Step 3: Freezing the Ice Pack
Let the gel pack freeze for about 2 to three hours. The differences in the freezing points of the rubbing alcohol and water will prevent the solution from freezing and instead give a gel texture.
Step 4: Additional Notes
If rubbing alcohol is not available, dish washer detergent, hair gel, corn syrup or salt can also be used in the same proportions.
