A bizarre and dangerous internet challenge is making a resurgence on social media and kids are ending up in the hospital from participating in the trend.
Although the "salt and ice challenge" has made its rounds more than once over the past few years, it's gaining popularity again among kids and teens, but many are ending up with accidental chemical burns. The seemingly simple challenge calls for kids to place salt and ice together on their skin. However, salt lowers the temperature of ice to as low as negative 17 degrees Celsius or 1.4 degrees Fahrenheit, and the effect on skin can be similar to frostbite. However, because of the redness and numbness from the ice, kids often don't realize that they are giving themselves potentially second-degree burns.
As a part of the "game" kids are seeing who can stand the pain the longest and are posting photos of their burns to social media as proof. The National Society For the Prevention of Cruelty to Children in the United Kingdom issued a warning to parents about the craze.
"It is important for schools keep a close eye on all emerging trends and we welcome the warning to parents [sic]," a NSPCC spokesperson told the Huffington Post UK. "The rise of social media has contributed to increasing peer pressure among children. This 'craze' [salt and ice challenge] is another clear example of the risks."
