So what DIY experiments did you perform as a child? I know that one
regular poster deliberately electrocuted his sister.

Stupidest one? Half filled a jam jar with sodium chlorate and sugar
mixture, screwed the lid on good and tight and threw it into a bonfire.

The 'pop' was very quiet, but it took ages for all of the bits to fall to
the ground. I suspect some achieved orbit.

Remarkably I escaped injury.

Electrocuted myself a couple of times (when I got bored with explosives I
moved onto electronics). And once to my eternal shame I blew the circuit
breaker for an entire block of labs and offices while testing a new new
'invention'.

Perhaps this is why I stay clear of power tools (the chainsaw idea was a
non-starter, and I've still not plucked up the courage to get an angle
grinder yet).
