A project box with large switch,  neon indicator lamp and  electrical cord that made the rounds at one of the summer jobs I had with a neat typewritten label that said

Handy Dandy Fuse Popper

1) Plug it in
2) Light goes on
3) Press button
4) Lights go out

The push button switch (50 amp or more rating) and a neon bulb indicator light connected in parallel across the mains.

It wouldn't work in Britain - our lighting circuits are always separate from the sockets, and plugtops have
their own fuse!  :-)

When I was young (15) and very foolish my mother's car battery was flat (low on charge, not as in pancake :-)
and I was given the job of removing it from the car and bringing it and charging it - there was no way to do
it while still in the car.

Having done so, the battery was sitting in the hall awaiting refitting to the car, and I thought I'd test it
to make sure it was charged... by quickly swiping a piece of thin wire (one core of telephone cable I think)
across the terminals... the resultant release of energy welded the last inch of wire to each terminal, and
vapourised the rest, insulation and all!  I was dazzled by the flash for some time.  Quite why it didn't burn
my fingers I will never know, but I now know I was very lucky not to detonate the gasses that could have been
around from the charging (Hydrogen and Oxygen in just the right ratio for an explosion).

When I look back at some of the stupid things I've done, I'm amazed that I've avoided a Darwin Award...

Cheers,
