The “salt and ice” challenge is going viral again. For Queensland mum Rebecca Etherington, this comes as terrifying news. Her teenage daughter is still suffering from when she did the challenge two years ago.

The challenge involves people putting salt on their skin, and then pressing an ice cube on top. The temperature of the mixture rapidly drops to well below freezing point, causing intense pain. It can result in injuries similar to frostbite.

In January 2015, Etherington’s 14-year-old daughter Hannah took part in the challenge at a sleepover.

Hannah ended up with a third-degree burn about the size of a business card on her leg. It quickly became infected, requiring treatment with antibiotics.

Etherington says Hannah has been left with an "horrific" scar.

As bad as Hannah's scar is, the "salt and ice" challenge has resulted in even worse consequences.

"I’ve heard of other kids overseas that did the same thing and it got infected, and they got blood poisoning and died because they hid it from their parents," Etherington says. "They didn’t want their parents to know."

Etherington is disturbed to hear that a new crop of kids is now taking on the challenge.
