Except in this case it’s not the electric shock that kills you. An arc flash is literally an explosion, creating a blast wave of molten copper and temperatures comparable to the surface of the sun.

One of the videos they showed during my arc flash training was a documentary of a guy who accidentally used a voltmeter on a live 2300V cabinet. The arc flash blew his clothes off and set him on fire. He stumbled blindly through the factory before finally collapsing.
We could have had it as early as 1793, but the ship carrying the metric standards was attacked by pirates.
Okay so this reminds me of something that happened in a college chemistry class and I was wondering if someone here can offer an explanation.
We were doing an experiment that first involved dissolving some copper into a solution, then chilling it to add another ingredient, then heating it on a hot plate. After doing all the other steps, I placed my beaker on the hot plate and turned around, then I heard a hissing sound. I turned back around just in time to see my beaker flying off the hot plate, off the counter, and smash on the floor.
My best explanation for this is that since the hot plate was already hot, some condensation from the previous chill step had dripped down, flashed to steam, and propelled the beaker off the hot plate.

It depends on the design of the toilet, and how much water it dumps into the bowl at each flush. Some toilet designs have a tank with a higher capacity than the bowl, so if it gets clogged then it’ll overflow. Pro tip: know where your toilet’s shutoff valve is, it’s usually on the wall just under the tank. If it looks like the toilet is about to overflow, just turn that valve off and you can avoid the mess.

Sure, but I can fix a carburetor with a wrench and a screwdriver. Can’t do that with modern cars.
