Sick of breadboards and soldering? Want to teach basic electronics in a whole new way? Electroninks is now selling a fast-drying, conductive ink designed to make learning about circuits fast and fun.

Made of silver flake, Circuit Scribe ink can be used to draw lines between batteries, sensors, lights and servos to make simple circuits. Just be sure to set your paper on top of a magnetic circuit so the parts don’t slide around!

The developers kit ($195) comes with 48 pieces, including two-color LEDs, NPN transistors, DPDT switches, potentiometers, a blinker, buzzer, motor, steel sheet, on-off switches, and 9V battery adapters. Classroom kits are also available, for the STEM teacher who wants to really wants to make an impression.

There are competing inks on the market, but the developers say Circuit Scribe is the only one that doesn’t require hours to dry. The only thing you’ll have to wait for, is the postman.
