I bought it before COVID but I opened the box just one week ago. It was wet (lots of stringing) but after a quick drying session it printed ok (photos coming soon). Then I put it back in my IKEA dry box
How quick is quick? I have a heated dry box, so all new filament gets at least a 24 hour spa treatment. If I know it's wet, it lives in it until color indicating silica gel no longer changes, then another day for good measure.
OP spooked it good. Next time announce yourself when you come into the room and this shouldn't happen. Also, do all that other stuff commenter's are recommending, but mostly the annoucing yourself.
The stress is from cooling the filament and then winding it around the spool. Lots of reasons why the plastic would weaken that stress might suddenly give way, but most of them involve time. If it wasn't completely cooled internally before being spooled, that would dramatically increase the stress (think Prince Rupert's drop).
Filament died of cringe 😔
after printing three Dick Butt in a row
Three Dick Butt? Those are rookie numbers, you gotta pump those numbers up!
Was it left open + maybe in a humid area? Brittle usually means wet filament.

You didn't dry it enough. You only dried the outside, the inside was still wet and brittle. Once you used up the dry stuff it broke.

Was it in an air-tight bag in that box?
They used heat shrink packaging, which doesn't look very airtight
Even the thick plastic bags are semi permeable. Eventually every sealed filament will soak up moisture.
Heat shrink packaging is typical and should be fine. Strange.
Looks like a defense response. Didn't sneak up behind it and scare it did you?
Is there a cucumber nearby?

Hi, filament expert here
This is not funny
Filaments only do this when they are under extreme distress
I can just hear it go "pssp, pssp" as it slides through the hot end
Edit: better comment
Can't fool me, that's clearly a pile of Twizzlers around an empty filament spool.
Red Vines
Mmm twizzlers...
Moisture.
Entropy?
Can I get that as a framed print?
This is the internet. Just do it.
Shitposting is a lot less effort.
Your bed needs leveling
You were trying to print big tiddy hentai statues and it rebelled.
Degradation over time?

Op says the roll is pre-Covid, so the time piece checks out.
You could sit there and feed each piece into the hot end one at a time, I've done that with spool ends but totally not worth it here :p
I tried it with the longer strings but looks like I have to throw everything
Makes perfect sense, beyond saving at this point. Good luck with the next spool, wait to unbox it until you're ready to print a few things in a row 😁

sorry, that was Cthulhu's spool :(
