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

Students are short-circuiting their school-issued Chromebooks by inserting metal objects like paper clips, pencils, and even pennies into the USB ports.

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.
