Stress Thermometer lie detector and biofeedback gadget : Shiny Shiny

Apparently when you lie, your hands get cold. So the thing is to get someone you suspect of being a liar to hold this while telling you a lie, and to watch the Stress Thermometer for proof. I suppose what could work would be if you snuck up on them while they were asleep, stuck it in their hand, and then shouted, "Did you eat my birthday cake that I saved all week and forgot about when I had to go care for my sick mother?" and see if the temperature changes. But if you need it for that, you may have bigger issues. [GT]
