not sure if this is the correct section for this. It wasn’t my mistake. but wow what a blast.. Probably a battery/phone in the dryer

What kind of camera was that? It was framed like a cell phone camera, which makes me suspicious that is was staged. The motion tracking made some sense, but why would the default pointing location be that dryer, and why would a surveillance camera have that aspect ratio?

If anything, though, I would maybe suspect a lighter in a pocket. I don't think a battery in a cell phone would be contained enough to cause that kind of explosion, but butane igniting in a lighter might.

That said, I am not an expert in explosions, but I do have a dryer an some pretty old and large NMC batteries!
 
shorts are always like that, it is enforced by YT.
The camera was focusing on moving parts - as that is the most common behaviour.

I don’t think a lighter could blow out the front of the store.

Didn't realize it was a Short. I turn those things off because of the annoying aspect ratio (and overall content). YouTube trying to be TikTok!

I wouldn't think a cell phone battery could either. NMC batteries burn fast and hot, but it requires containment to cause an explosion.

I actually like the idea of fumes from the clothes. That could fill up the inside of the dryer and combust pretty fast.

That said, dryers have fairly large vents, so the combustion would have to be pretty fast to blow the door off.

Needs more testing...

From what I seen of lithium cells being punctured there is an explosion and I’d assume more so in a contained space. The containment was the door sealed shut. Not 100% sealed but contained more so then being out in the open. Then it blew open from pressure then the air then the flames.

I would think this would be more of an overheating than a puncture.

I worked on some open source projects back in the early days of quadcopters. The only non-induced Lipo fire that I've seem was when a developer was working on an ESC (brushless motor controller), and he was recording a test when the battery overheated in his apartment! It just started spewing flames, and he was able to sling it into a trash can and put it on his balcony.

This is more what I would expect, and with much bigger batteries:



This one is pretty violent, but still not really an explosion:


Actually, this is pretty definitive:


And the movement was actually staged...
 
if all those above were slightly contained I’d assume it would be a lot more dramatic and with constant fresh air being pumped into the containment
