The Colorado Springs Fire Department is warning parents and educating children about a viral social media challenge making its way through local schools, according to a Friday news release.

The challenge on the platform TikTok instructs students to put the tip of their pencil or a piece of metal into the charging port of their Chromebook, which causes a spark.

Fire Department spokeswoman Ashley Franco indicated this spark has resulted in the laptop to smoke or catch fire, and poses more serious risks of explosion. When the Chromebook catches fire and releases toxic fumes, it makes it difficult to extinguish.

The department says the challenge has made its way into schools in the Pikes Peak region. As of Friday, there have been “at least 16 incidents” of the trend, according to the release.

Students caught participating in this challenge are sent through a youth fire setter intervention program taught by the Colorado Springs Fire Department which teaches fire safety awareness. The Fire Department has also educated school officials about the challenge and how to handle the situation.

Fire crews are urging parents to talk with their children about this challenge and the dangers behind it to prevent it from continuing.
