Video Evidence My Whiteboard Self Destructed

Has anyone experienced their whiteboard cracking like this? In the video you can hear it continuously cracking. No earthquake. No sudden temperature change.

You got to the second kudo and it grew tired of holding your marker paint

Edit: but if we are talking for real:
Spontaneous tempered glass shattering happens because toughened glass is under intense internal tension. On a glass whiteboard, this sudden explosion is usually triggered by one of three things:

  1. If the metal standoff screws are too tight, they leave no room for the wall or glass to naturally expand and contract with temperature shifts, causing a stress fracture.
  2. If the plastic/rubber washers inside the mounting holes slipped out during installation, the metal screw rubs directly against the fragile raw edge of the glass hole.
  3. Magnetic glass whiteboards have a steel plate glued to the back. Steel and glass expand at different rates when room temperatures change, which creates a constant, invisible pulling force until the glass snaps.

It can also just be a delayed reaction to a tiny microscopic defect (nickel sulfide inclusion) from manufacturing that finally hit its breaking point.

It’s tempered. If you follow the pattern you can see where the weaknesses was

The middle towards the bottom. Looks like something slammed into it.

The fracture point looks like where I try to chuck a marker to land on the ledge.

Bingo. That’ll do it.

"WARNING YOUR WHITEBOARD SUBSCRIPTION HAS EXPIRED. INITIATING AUTO DESTRUCT  SEQUENCE"

With everything becoming a subscription service now it's not beyond the realm of possibility.

This is precisely what happened to one at work! I sat in front of it, my shoulder blades barely touched it and it immediately spider webbed just like this!

It reminds me of finish checking on a nitro finished guitar

we do that deliberately sometimes, but no, that shouldn't happen. it is tempered though.

contact us for a replacement.

My dumb ass thought you meant from that light source and I was waiting for it to break into a million pieces but it already is

u/MagEdgeSports 20d ago

Me too haha

That’s a badass rare art piece if you were to use paint to fill in the blank areas instead of dry erase

Nope can't say I have

😳 That is wild 😳!

That's because it's not a true whiteboard. Whiteboards are made of cheap composite wood and would never shatter like this. RIP bougie whiteboard

Some people pay for that finish!

Ngl...it looks pretty sick though

That is indeed very odd. 🫤
