My boss Robert gave me this fearsome-looking device for my birthday. Once your hand is strapped in, it registers your heartbeat and sweat levels and then, as you are asked questions, it works out whether you are lying or not. Anything it thinks is a lie is punished with an electric shock! I used it with one of my classes this weekend and the students loved it. You can only get away with this sort of thing in China, though. Can you imagine the British media backlash if I had been caught "asking young girls embarrassing questions and inflicting electric shocks". I'd be struck off!
(Thought about using it on mother-in-law, but didn't want to overload it!)
