(AP) — A 13-year-old northeast Kansas boy is recovering from minor burns on his face after another boy threw flaming hand sanitizer at him.

The incident happened Wednesday at a middle school in Shawnee.

Police say the 12-year-old poured hand sanitizer on his own hand, lit it on fire and flicked it toward the 13-year-old. A school nurse treated the older boy’s face before his parents took him to a doctor.

The 12-year-old is facing juvenile charges. Investigators say he told officers he learned what he thought was a party trick from an older student.

Police said the incident appears to have been meant as a prank but could have caused serious injury.
