Flexible Ice Pack
Every now and then life hands you a situation that says, “I need an icepack!”
Maybe you’ve had an injury or a sprain, perhaps a hurt child needs to soothe a wound. Or, maybe you just need to keep your lunch cold. These ice packs are great because they are flexible, which makes them perfect for conforming to an injured ankle or other body part. Water alone would freeze solid and be rigid and uncomfortable. This ice pack is made of a mixture of Isopropyl alcohol (rubbing alcohol) and water, so they only partially freeze and remain flexible. The science behind it is that the rubbing alcohol keeps the water from freezing completely. And this ice pack stays cold for a good 20 to 30 minutes.
To make this DIY ice pack, mix one part rubbing alcohol with three parts water in a plastic zipper bag. After filling the bag get out as much air as possible and seal it. Place the filled bags on flat surface in the freezer for several hours. When you take the ice pack out of the freezer, after about 3 to 4 minutes at room temperature, it will become flexible.
