DIY reusable gel ice packs
These are super easy to make and useful. They work great for both first aid and keeping picnic lunches cool. I like to put them in freezer bags, and double bag just to add some durability. I added some food coloring to these-I like to keep the food bags and my injury bags separate, so I color code them to keep organized. (I keep the color dilute so it won’t stain anything if it breaks). Here’s the formula:
1 part isopropyl
2 parts water
Bag and freeze
