I found this clever ice pack DIY project on Wise Bread. The article is about unusual uses for Original Dawn dish detergent. What I like about this project is that having these in the freezer will help during a power outage and be a handy if I run out dish detergent.
The instructions are:
1. Fill a sturdy freezer bag halfway with dish soap.
2. Double bag it for leak protection.
3. Cover with fabric (I use a clean sock) to protect the plastic.
4. Keep in freezer. It will freeze to a slushy consistency which makes is easier to wrap around sore joints or fit around foods in your lunch bag.
The instructions insisted that only original Dawn would work, but I found another tutorial insisting only green Palmolive dish detergent would work. You can see pictures of it on Runner’s World community forum.
What I like about this ice pack solution is that it is not just reusable, but easily recycled when it wears out. I will keep moving the detergent to a new bag or just clean with it. No waste!
I made my ice pack with lemon yellow Ajax because that is what I had on hand. It turned out slushy and pliable.
Note to self: I need to experiment with cooler bags with ice packs to increase their cold-retention. Living in Hemet makes me think twice about shopping for cold foods in the summer. If I am not going straight home afterward, it’s not convenient.
There’s a science lesson in these ice packs, but need to look up colligative properties and freezing point depression.
