My high school science teacher used to share anecdotes from his days in electrical repair.

He said his coworkers would sometimes toss a television capacitor at each other as a prank.

Those capacitors retained enough charge to give the person unlucky enough to catch one a considerable jolt.

I remember smashing a broken monitor as a kid for fun, hearing about the implosion stuff, and sadly found the back of the glass was stuck to some kind of plastic film that didnt allow the pieces to fly about :(

I can't still get over how we used to put them straight in our faces, yet I never knew of someone having an accidental face reshaping ever.
