Japanese startup company AgIC has created a pen with conductive ink that allows you to draw electrical circuits. The name is a nod to the chemical system for silver, Ag, along with the initials IC, which stand for “Ink Circuit”. According to Vocativ, the Circuit Marker is a pen with silver-based, electricity-conducting ink that allows you to turn custom artwork into a functional electrical circuit. It feels just like a normal marker pen. However using the conductive properties of silver found in the ink, you can turn your doodles into a functioning electrical circuit. Besides being a way to create glowing city drawings, the pen, and its conductive silver ink can be used to teach children of all ages how circuits work. In fact, the company’s mission is to make electric circuits more accessible to everyone. In 2015, AgIC started a Kickstarter campaign for the Circuit Eraser, and now their product is commercially available. You can buy a silver ink pen for yourself on the AgIC online store for $15, the Circuit Eraser is $8, and the special paper is between $10 and $50. Although bear in mind, they can only guarantee it works if you also buy their specialized paper.
