    Somewhere I have a 'dangers of electricity' demo I use for scouts (or did ages ago, before lockdown when we could meet up) that is just a couple of scrap forks on a wooden board facing up, in series with a push button and key switch , that runs from mains with a socket for a series current limiting heater. (so if you short the forks and press the button, all that happens is the heater comes on full)


    This will do hot dog sausages to a sizzle quite well,and hammers home the point about entry and exit wounds in a non-lethal but hopefully memorable way.


    It is also quite fun to do a pickled gherkin with the lights out, as the salty vinegar water dries out, you get a lot of orange flashing from inside the pickle that I think, but have not verified, is the sodium D line spectrum of  older street lamp fame.


    The key switch means it cannot be made live if I am not beside it, youngsters being  curious as they are.
