At least three students at a Chicago high school were injured on Wednesday after they tried to warm hot chocolate with gas burners, the New York Daily News reported.
The lab fire erupted around 10:30 a.m. at Northside College Prep High School.
"They had a little accident in a lab involving a gas burner," said fire department spokesperson Larry Langford.
Firefighters, paramedics, and a hazmat team arrived at the school and are still trying to determine whether it was the gas or the chocolate that caught fire.
One student reportedly suffered severe facial burns and was rushed to a hospital is serious-to-critical condition. Three other students were also transported to hospitals, who listed two in fair condition and one in good condition.
Immediately following the blast, all students were evacuated from the school. According to a report by ABC News, the students were allowed back inside around 11:15 a.m.
Earlier this year, a lab fire at the Beacon School in New York City left two students burned.
Alonzo Yanes, 16, was seriously injured and rushed to Cornell Medical Center's burn unit.
"His skin - a lot of it was melted and scabbed," said a classmate, Jeremy Reynoso. "He was on fire for a good minute. I saw his ear was melting. The skin was peeling. His face was red. Afterward, he wasn't talking or moving."
A second student, Julia Saltonstall, 16, suffered less serious burns to her head, neck, and arm.
