Homemade Ice Packs:

This one isn’t so quick, but it’s still easy to make on your own.
Start with a Zip-lock bag (one that will seal very well) and fill it with one part rubbing alcohol and two parts water. The alcohol keeps it from freezing completely, so you end up with a bag of slushy liquid, which is ideal for placing around your joints.
This might get a little cold, so put a towel between the bag and your bare skin when you use it! (That’s one thing that’s awesome about this pack. It stays colder much longer than a typical store-bought ice pack.)

Bonus tip: Put some blue food coloring in there and it will look just like the ice packs you buy at the sporting goods store!

Bonus tip #2: To make this one even easier, skip the water/alcohol mixture. Instead, fill the bag with dish washing soap (such as Dawn or Palmolive) and freeze. The soap won’t freeze, either, so it will conform to your body nicely!
