Youtube suggested I should watch this video – I couldn’t resist.
Having touched a live 240V wire by mistake was a memorable experience (I still remember it even though it was twenty years ago), so I am not too keen on trying this pencil hack out and I suggest you don’t either.
The idea is interesting, though. An explanation how this works would be nice.
Again, I don’t suggest that you try this at home (or at work, or while out and about).
