Charlotte-Mecklenburg Schools principals are warning parents about a new TikTok challenge. The trend is known as the ‘TikTok Chromebook Spark Challenge.’ The trend includes tampering with Chromebook charging ports or power supplies to create sparks. School officials say the challenge could cause damage to school property and inflict serious injury.

The challenge involves sticking a piece of metal like a paperclip, graphite or push pin in the USB port of their school issued laptop in order to cause sparks and possibly set it on fire.

The “Chromebook challenge” involves using objects such as push pins, staples, paper clips, metallic gum wrappers and graphite, found in pencil lead. They are inserted into USB or charging ports, under keyboard keys, or near the batteries to deliberately short-circuit the devices.
