LED mittens light up whenever you shake hands

The act of shaking hands dates back centuries, fast forward to today and you get a pair of LED-equipped mittens which will light up whenever you shake hands with someone else. This was specially made using two pieces of conductive fabric that are located around the thumb and across the palm, and when touched by bare, ungloved skin, the LED will turn on. Heck, if you are enterprising enough, you can even knit your own mitten as well as the conductive yarn.
