Hand Warmer
During the winter months when the weather is cold, hand warmers can give the user quick and comforting heat to their hands. Unlike the tons of heating products available on the market, hand warmers seldom need to use electricity and in many cases they do not need to use batteries, this makes hand warmers extremely portable and simple to use. Hand warmers save many a person from the harsh effects of cold weather and usually work using environmentally friendly substances. The warmer uses a chemical reaction between its ingredients which include water, vermiculite, activated carbon, iron, and salt.
The process used to create heat in hand warmers is done quickly and efficiently. The iron in the warmer is introduced to oxygen and produces heat, the salt is the catalyst making the warmer heat faster, and the carbon spreads the heat over all of your digits. Then the hand warmer uses the vermiculite as an insulator to retain the heat. This gives the user quick and safe heat for your hands and it is great in protecting your hands from frost bite. It is important that if you are going on a camping trip or on a long vacation where you will be driving, it is always a good idea to carry a hand warmer along with you, in order to protect yourself.
