Just a small Canadian town with very little else to do...
This school used to put students on detention in the office where the secretary + principal could keep an eye on them (so the teachers actually got a break instead of classes then detention supervision). For some reason the room they'd put you in also had a display for all the cameras in the school, just slowly flipping between each one.
Just meant all the school bullies, pranksters, and general troublemakers knew exactly where to stand so they weren't caught on camera XD
To act as a fuse, the tab needs to reach 660 degrees celsius, and if the breaker pops, that means the breaker acted as the fuse.
I can tell you from experience; both occur.
Such a thin piece of aluminum across 120vac super heats so quickly that it basically vaporizes, faster than the breaker can react. That metal vapor allows an arch to form still passing excess current which is what finally trips the breaker. (standard breakers take time to trip, longer than fuses in many cases; this is intentional design. GFCI breakers are a different story.) Sometimes this arc doesn't form and the breaker doesn't trip; but it usually does.
Once tripped, the vapor has time to dissipate so the short clears and the breaker can be turned back on.
None of this is advice. Someone asked about dumb pranks I've pulled in school. I'm just discussing the past; not making recommendations for the future.
Na, the aluminum acts as a fuse and breaks the circuit almost immediately. It makes a bright flash and a loud sound, but it's over in a second with no real harm.
That's not to say I'm recommending this at all, it's definitely a pretty stupid prank; just that it doesn't cause nearly as much damage as you might think.
Kids have lots of stupid ideas and saftey isn't exactly the first thing they consider...
At least I never heated the handles of the tool cabinets with the blow torch in shop class. Had two separate classmates pull that 'prank'.
Pull the tab off of a pop can. Turn off the switch on the power bar that the teachers computer is plugged into. Unplug the computer, slip the pop can tab over the live+neutral prongs, plug it back into the still off power bar and wait.
The teacher goes to use their computer, finds it's not turning on and looks at the power bar.
Switch flips, 'BANG', scream, lights go out (breaker popped).
FolderSync selectively syncs files/folders from my phone back to my server via ssh. Some folders are on a schedule, some monitor for changes and sync immediately; most are just one-way, some are two-way (files added to the server will sync back to the phone as well as uploading data to the server). There's even one that automatically drops files into paperless-ngx' consume folder for automatic document importing.
From there BorgBackup makes a daily backup of the data, keeping historical backups for years with absolutely incredible efficiency. I currently have 21 backups of about ~550gb each. Borg stores this in 447gb of total disc space.
The middle school that I went to had a ~14" crt tv hanging from a sturdy ceiling mount in every classroom.
Displayed things like school bulletins and daily morning announcements, there was a couple educational channels, and a vcr input. Every now and again there'd be some sort of presentation instead of hauling everyone into the gym for a school assembly.
Anyway; it didn't take me very long to figure out the universal remote that came with the satellite receiver at home could be programmed to the school TVs. I'd mess with the one in class, or skip classes and mess with the ones in my friends classrooms through the windows; cranking up the volume and blasting Bill Nye or the announcement channels awful elevator music. Weekends, I'd do a lap of the school turning on all the TVs I could reach from outside and maxing the volume for whoever opens on Monday, or just turning them off again so it blares at whoever turns it on next.
If I ever look up at the night sky and see a billboard shining down at me from space (literally or through some kind of mind/vision altering tech like nuralink) I'm becoming an anarchist.
The rust, sure; but the rain seeping down and pooling in the frame which has no drain holes, is not. Electronics don't like sitting in pools of water long term.
