I fondly remember how I electrocuted myself a few times too! One of my first stupid things I did which I still remember was to cut off a plugged clothing iron (with a metallic scissors). Maybe it's safer for kids nowadays but they're missing the real fun.
Only after years I realized how kind it was of my parents to allow me, without saying anything, to take their first cassette player (and other stuff) apart.

Edit: many hanzi-labelled PMVs on https://so.youku.com/search_video/q_pmv?searchfrom=1 (I found the sort dropdown, but don't know enough hanzi to search by date there.)
The concepts used to operate a CRT or VCR or even an older computer would have been easier for me to figure out and poke and prod as a child than newer devices which operate on microscopic scales with everything integrated. I would think a child today would need much more background and reading before they could begin to comprehend what's happening in an iPad versus looking at something that moves, and manipulating it to see what happens. Or at least test things with a multimeter.
For example, I could take apart a VCR with a couple basic tools and no input from my parents (who were always busy working and didn’t know English). But I might have needed some guidance on where to get started with a Raspberry Pi and obtaining one, guidance I never would have received from my family.
I preferred the stills over the more explosive ones as I optimistically hope the devices in the stills are reassembled.
biological things (not safe for vegetarians):
but I must admit, I prefer my biological things intact and sorted by max speed: https://books.google.ch/books?id=2lQEAAAAMBAJ&pg=PA69&dq=rec...
