Remember kids, don’t try everything you see online.

There have been multiple incidents of students in Prince George’s County sticking objects into their school-issued or personal electronic devices, causing fires and smoke, according to the Office of the State Fire Marshal.

State officials said it’s because of a TikTok trend that’s being called “the Chromebook challenge,” where students stick pencils or other metallic items into charging ports, causing a short circuit.

A Prince George’s County Public Schools spokesperson said there have been 12 reported incidents of students participating in the challenge, all in middle or high school. That’s out of about 132,000 students in the system.

The State Fire Marshal said the reported incidents in Maryland have “resulted in sparks and smoke” and some cases of batteries catching fire.

Acting State Fire Marshal Jason Mowbray said it was important to teach students about how dangerous participating in the “challenge” can be.

“It is crucial that parents and educators work together to promote a culture of safety and responsibility regarding electronic devices,” Mowbray said in a statement.

The Maryland State Fire Marshal said they were only aware of reported incidents in Prince George’s County as of May 9.

Police in New Jersey charged a 15-year-old with arson after the student “intentionally manipulated the device as part of a social media challenge trending on TikTok, resulting in the Chromebook smoldering and posing a fire risk,” according to NJ.com.
