Lie Detector
 

It may look like an Altoids tin, and it is. But it is also a lie detector. This device measures skin resistance. When people lie. they become nervous. When people are nervous they sweat which changes the resistance of your skin. This is how polygraphs work. This device though sends the data to a computer via USB and displays the results on a graph. If the graph spikes it means the resistance decreased which means more sweat which means that person is nervous which means they may be lying. Not 100% accurate at all, but fairly accurate. More or less just for fun
