We all love a fun internet trend. Planking. The Ice Bucket Challenge. The Mannequin Challenge. But some of these "challenges" are not only dumb, but dangerous too.

The salt and ice challenge is just where you put salt on your skin then put an ice cube on the same spot and see how long you can hold it. But the salt lowers the temperature of the ice which makes it freeze your skin faster. Then it starts to damage your nerves and blood vessels. soon enough you will never grow hair on that spot again. Then you'll lose feeling there. And you might even end up with a black dead leathery patch of skin that looks awesome during swimsuit season.

In other words, just don't do it,
