This is your News You do not Need podcast.

I spent today scrolling through the news, looking for something that absolutely no one needs to know, and the universe did not disappoint. While the world argued about politics and storms, my favorite headline was: “Chinese Students Crack Code Of Classroom Phone Safe Using Chalk Dust, Internet Reacts.”

Somewhere in China, there’s a teacher who thought they’d finally beaten teenage attention spans. They bought one of those lockbox “phone safes” for class. You know the idea: kids drop their phones in, teacher locks the box, learning happens, nobody’s scrolling during algebra. A beautiful dream.

Enter a group of students who apparently watched one too many heist movies. The safe had a little rotating dial or keypad, and instead of accepting their phoneless fate and, say, paying attention, they decided to go full Mission: Impossible with… chalk dust. Not AI. Not quantum computing. Chalk. The same thing you use to draw stick figures and passive-aggressive notes on the blackboard.

According to the report, they basically dusted the lock area with chalk, spun or pressed until certain spots smudged differently, and used the pattern to figure out the correct numbers. In other words, they turned a ten-dollar classroom gadget into a forensic crime scene. CSI: Homeroom.

And it worked. They opened the phone safe. Which means at some point the teacher walked back in, proudly ready to free everyone’s phones like some benevolent screen-time Santa… and the box was already open. Just a pile of teenagers pretending they had no idea what happened, while one kid frantically clears chalk off their fingers.

The story says people online were divided: some were impressed by the ingenuity, others were deeply concerned that this is what students are using their brainpower for. Personally, I love that a generation accused of having “no attention span” will spend an insane amount of time reverse-engineering a lock just to check TikTok for 90 seconds. That is commitment.

Imagine the parent-teacher conference. “Your child is failing math, but the good news is they’ve independently mastered practical cryptanalysis and low-budget physical security bypass. Have you considered a career in cybersecurity, or possibly supervillainy?”

My favorite part is that the whole scheme depended on chalk dust, a material teachers have spent decades trying to get rid of. Whiteboard markers replaced it, smartboards replaced those, and yet chalk has risen from the dead, not to help with equations, but to jailbreak a phone prison.

Some commenters pointed out this might be a wake-up call for schools to upgrade to better safes. Honestly, at this point, no matter what you buy, some 15-year-old with boredom, Wi‑Fi, and a half-hour study hall is going to figure out how to crack it with a household item and a YouTube tutorial. Give them a biometric lock and by next week someone’s opening it with a gummy bear and a hairdryer.

And the best part? You did not need to know any of this. Your life would’ve gone on just fine without ever learning that somewhere, in a classroom far away, a phone safe was defeated by the same substance used to draw hopscotch squares. But now the information is in your brain forever, taking up space where something useful could’ve lived, like your online banking password.

So if you’re listening to this while procrastinating on something important, just remember: at least you’re not dusting office equipment with chalk to hack your way back into Instagram. Yet.
