The process of making a pocket heater

The heater requires sodium acetate. It is available over the counter at chemical stores. You can also make the reagent at home from baking soda and vinegar (https://home.washerhouse.com/en/3813-goryachiy-led.html). From ordinary sodium acetate you need to make trihydrate. To do this, at 82 gr. 54 grams of crystals are poured. water.

Sodium acetate trihydrate is placed in a zip bag. It is closed and lowered into boiling water, where it is cooked for 10-15 minutes. It is necessary to melt all the crystals; to do this, the contents of the bags must be stirred periodically.

The bag of melted acetate must be removed and allowed to cool.Although the substance freezes at +58°C, this will not happen, since there are no centers of crystal formation in it. In the future, if you throw one crystal of sodium acetate into the heating pad and close the bag, the substance will instantly turn into hot ice. It will heat up to almost +60°C and will remain warm for 20-30 minutes.

By keeping a couple of sachets and activation crystals in stock, you can warm your hands at any time. To restart a used heating pad, you need to boil it again in boiling water and then dip the crystal to activate it.
