Cold Bag Views
Have you seen these Hot/Cold bags before at the store? I had noticed them hanging off of freezer door handles for over a year before I broke down and bought one. I was shopping an hour south of home and located a flavor of sherbet my father had been desperately seeking for months; I knew I had to bring some home. I didn’t have high hopes for the bag but I hoped it would at least keep the product somewhat cool so that dad could have some cold soup by the time I reached home.
At the checkout my checkbook was unhappy but I refused to let it upset the delirious high I was on. Out at my car I placed all of my cold items carefully into my special bag and made sure each of the snaps clicked. I placed the bag in a foot well to prevent unnecessary bouncing and ran episodes of the Food Network through my mind trying to think of what to do with my bounty.
It’s been over two years since that escapade into the Hot/Cold bag territory and I’ve never looked back. I mention it to all of my friends and relatives as a great piece of equipment. Just stick it next to the front door and take it back to the car next time and you’re ready to shop at a moments notice – you don’t need ice – you don’t need heat packs, it simply works with the heat or cold from the items in the bag. For the ware and tare you get out of each bag I say its well worth the small investment and in the end when they need to be turned out to pasture they don’t owe you a cent.
An instant cold pack is a device which consists of two bags, one containing water which is inside a second bag containing ammonium nitrate. When the inner bag is broken by squeezing the package, the ammonium nitrate is allowed to dissolve in the water in an endothermic reaction. This reaction absorbs heat from the surroundings, quickly lowering the pack's temperature.[1]
