VIDEO: A Heritage High School student has a warning for other kids after 76% of his body suffered burns when he tried a TikTok challenge. Mason and a group of friends saw people playing with lighters and spray paint cans on TikTok. They then decided to try it themselves trying to start a fire to stay warm, but the can blew up and flames engulfed his body. With second and third-degree burns all over his body he had to go through skin graft surgery and was intubated for about three weeks so he could recover. Doctors expected him to be in the hospital for about six months, but Friday he's up and walking and has a message for other kids. "Don't do stupid things. Don't try new things. Don't try to be different and make an impact and try to go viral," said Mason Dark.
