In July, a 10-year-old boy from North Carolina suffered severe burns after attempting the challenge. A number of videos have been posted to YouTube showing people dousing themselves with pots of boiling water but their veracity remains unclear.
Most recently, 11-year-old Jamoneisha Merritt from The Bronx, was rushed to the burn unit after friend's allegedly poured boiling hot water over her.
The breathtakingly risky Hot Water Challenge appears to have started two years ago but is now sparking urgent warnings following high-profile casualties.
The parents know their son made a mistake and they say they've questioned him about the decision, but right now their focus is on his recovery. It's gained popularity among children, but can result in severe injury and even death.
The 11-year-old remains in hospital after suffering severe burns in the incident in NY.
Although there were rumors that the two girls were "best friends", Jamoneisha's mother, Ebony, said that the 12-year-old and her other friends actually bullied her daughter in the past. As reported by People, an eight-year-old girl name Ki'ari Pope lost her life a few months after she was dared to drink boiling water via a straw by her cousin.
The little girl, from Florida in the United States, had to receive a tracheotomy but died after a shortage of breath left her unconscious.
"Parents, talk to your kids about these challenges", Diane Johnson, Pope's aunt, told CBS 12. Merritt's mother has blamed the incident on the Hot Water Challenge; Merritt's cousin said that Merritt "and her friend got into an argument and she told her if she goes to sleep they were going to do something to her".
And know how your kids are using this technology, how they're consuming it, and what it's doing to them in terms of attitude changes.
Videos on YouTube suggest the craze extends back to 2015 in America.
Most do not show the after effects but some do post follow-up footage of victims having suffered scarring.
And Merritt isn't the only one who has suffered thanks to this idiotic challenge.
"When tap water reaches 60C - water boils at 100C - it can cause a third degree (full thickness) burn in just five seconds".
NHS advice recommends treating burns with lukewarm running water for 20 minutes and taking the person to hospital if the burns are bigger than the affected person's hand, cause white or charred skin or cause blisters.
