It’s 29˚F outside and I can’t help but feel that chill creeping into our store. Sure, I’m wearing two jackets, jeans, a hoodie, beanie and a hat but what’s really keeping me warm are the Grabber Hand and Toe Warmers. I was curious and thought I would give them a try to see how well they worked and was quite pleased with the results.
Naturally, I wondered how these little pouches were able to get so hot and keep me warm for an extended period of time. I gathered this bit of information from Grabber’s website and thought it would be a great idea to share with you:
These warmers operate on a chemical reaction with air similar to rusting. The warmer ingredients are iron, water, cellulose, vermiculite, activated carbon and salt.
The heating process takes place in this fashion:
• The iron in the pouch, when exposed to oxygen, oxidizes and therefore produces heat (aka, “Air Activated”)
• When iron oxidizes it produces iron oxide, more commonly referred to as rust
• The salt acts as a catalyst
• The carbon helps disperse the heat
• The vermiculite is used as an insulator for the purpose of retaining the heat and the cellulose is added as a filler
• All of these ingredients are surrounded by a polypropylene bag
• Polypropylene allows air to permeate the ingredients while holding in moisture
I usually have pouches in each glove and show and since they are so inexpensive, I keep a number of them in my truck during the winter season for days such as this. They are great for any outdoor activity whether working or playing and they save me on cold days in the store especially in our warehouse area.
