Firefighters and school districts in Colorado are warning about a potentially dangerous TikTok challenge that has gone viral.

The Chromebook Challenge, named for Google's line of laptops, encourages students to insert metal items into the USB port on their school-issued computers, intending to create sparks, smoke and possibly a fire.

Students are jamming objects inside Chromebook ports to cause them to smoke or catch fire, prompting TikTok to block searches for the challenge and remind kids not to be stupid.
