TikTok is full of entertaining cat videos, humorous dances, and yes, even challenges -- the famed ice-bucket challenge has returned and is promoting mental-health support. But now a dangerous TikTok challenge is spreading through the short-form video app and through schools across the US.

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.

A Texas district has joined a growing list of U.S. schools warning of a dangerous social media trend encouraging students to destroy Chromebooks.
