> Which screwdriver is the right size to stick in this electrical socket?

Note that this is a legitimate technique in UK sockets.

The live and neutral pins have a little gate over them that is retracted when you insert the earth pin, so you need to first stick a screwdriver into the earth pin in order to get your fingers into the live pin.

I can't parse if this is humour or a mistake. Putting your fingers on the live pin is not a great idea, trying this to get an euro 15 plug into an UK socket, also not great but in a different category.

Well, there's also a mains tester screwdriver which is a legit tool that you stick into a socket and also participate in the electrict current loop for the light on it to light up.
