This Incredible Drawing Pen Transmits Electricity On Paper With Its Special Silver Ink

Tokyo-based startup AgIC has invented a marker pen that transmits electricity on paper using a conductive silver ink. Place an LED light and a battery on glossy photo paper and draw a line of any shape to connect the two. The light comes on as the silver ink conducts electricity between the LED and the battery.

The pen lets you design a circuit of your choice and if you let your imagination run wild, you can come up with some crazy results. Watch below as the circuit pen brings a miniature town to life in this beautiful video by Japanese infrastructure firm Kandenko.
