At first I thought people were joking. But it turned out that people do put this thing on their joints. They also warn that there will be a type of burn.
This is not a burn, brothers. This is frostbite.
The story of ice and salt echoes the story of capsules with detergent. These were all idiotic challenges on the network, from which a lot of jerks suffered.
I will explain. Ice is often used for bruises and joint pain. This is regular ice without any additives. On the skin, such ice creates a temperature of about zero degrees.
Salt is a different story. Salt lowers the freezing point of water. If salt is mixed with snow, then when this mixture melts, frost will turn out to be minus 15 - 20 degrees.
Here it is a matter of the transition from solid to liquid.
Imagine heat and sweat on your forehead. Why is it needed? It evaporates and cools the skin.
If the liquid is converted to gas, the temperature decreases.
Remember a cotton swab with alcohol used to wipe your skin? If you blow it will get cold.
I have a friend who froze a couple of fingers on his hand when in winter at minus 30 he poured cold gasoline into the gas tank from a canister. The gasoline was already cold, and when it splashed out onto your fingers and quickly evaporated, its temperature dropped even more.
This is how climbers who use liquid fuel for their tiles get frozen.
We talked about a liquid that turns into a gaseous state. But there is still something solid that turns into liquid. This process is also accompanied by a decrease in temperature.
The salt makes the snow melt. It turns from solid crystals into a liquid. While the melting process is in progress, this mixture is cooled. Maybe even minus 20 degrees.
Not only do the ice floes melt, but the salt crystals themselves dissolve. The dissolution process is also accompanied by a decrease in temperature.
In short, if you make yourself a cooling mixture of snow and salt, you will get frostbite, and a piece of skin will fall off. Then the rest of his life this place will be very sensitive to the cold. Turn on your brains in time. It is good for your health.
