A dangerous TikTok trend has put students, schools, and first responders on high alert. Known as the “Chromebook Challenge,” the viral stunt encourages kids to insert metallic or conductive objects—like pencil lead, paperclips, or push pins—into the charging or USB ports of their school-issued laptops. The result? Devices have overheated, produced toxic smoke, and in some cases, sparked minor fires, prompting urgent warnings from school districts and fire departments across the U.S.
What started as a seemingly harmless experiment has morphed into a public safety concern, with school officials now warning parents to speak with their children about the real-life consequences of participating in such challenges.
New Hampshire Schools Report Spike in Incidents
The situation escalated recently at Cooperative Middle School in Stratham, New Hampshire. On May 8, the school sent home a letter to parents warning them about the trend. Principal Drew Bairstow explained that in just three days, the Exeter Region Cooperative School District had seen more than a dozen cases of students intentionally inserting foreign objects into their Chromebooks.
“These items—like mechanical pencil tips or paperclips—are conductive and can easily damage internal components,” the letter read. “In several cases, the laptops overheated and became completely unusable. It’s a major safety risk and it voids the warranty.”
But beyond broken laptops, school officials fear the bigger threat is fire and toxic fumes. Damaged lithium-ion batteries, like those used in Chromebooks, can swell, release harmful chemicals, or ignite when short-circuited. The school made it clear: students caught participating in this challenge could face disciplinary action and may be held financially responsible.
“This isn’t just a prank. It endangers everyone around them—classmates, teachers, and even families at home,” the principal emphasized.
Fire and Smoke at New Jersey High School
The risks of the challenge became more than theoretical when a student at Belleville High School in New Jersey decided to give it a try. The result was a close call. According to Belleville Fire Department Captain Chase Hamilton, the student’s tampering caused the Chromebook’s battery to swell and start smoking in the classroom.
“It got hot, fast,” Hamilton recalled. “When I entered the room to investigate, the smell was strong. We were lucky it didn’t lead to something more serious.”
Hamilton, who is part of the fire department’s arson investigation unit, warned that lithium-ion batteries are volatile when mishandled. They can undergo a reaction called “thermal runaway,” which may lead to explosions, fire, or the release of harmful gases.
“Even a little smoke from these batteries can be dangerous to inhale,” he added. “This isn’t a joke. Someone could really get hurt.”
Thankfully, no injuries were reported at Belleville High, but the scare prompted local fire officials to urge other districts to talk openly about the risks of tampering with electronic devices.
TikTok Takes Action
With the trend gaining traction, TikTok has removed videos and hashtags related to the “Chromebook Challenge.” The platform now redirects searches to a safety advisory that warns users about the dangers of online challenges and provides resources for recognizing harmful content.
A spokesperson for TikTok told ABC News that the company is committed to removing content that violates its policies around dangerous behavior.
Still, the platform’s response hasn’t stopped the trend from spreading. School districts are now taking matters into their own hands, communicating directly with families and students to address the threat head-on.
A Call for Digital Awareness
The incident has become a teachable moment for parents, educators, and students alike. Digital responsibility and online peer pressure are now front-and-center topics in classrooms and homes.
Schools in the Exeter Region Cooperative School District are urging families to talk to their kids not just about the Chromebook Challenge, but about the broader consequences of engaging with viral content. Meanwhile, fire departments like Belleville’s are encouraging schools to hold safety seminars on battery hazards and appropriate tech use.
“This isn’t just about one trend,” said Capt. Hamilton. “It’s about helping students understand that what they do online can have serious real-world consequences.”
