Did you know that graphite is conductive? Which makes these pencils the perfect tool for quickly inventing with drawable circuits. No need for a physical button, just draw circuits as lines, circles or any shape you desire. Clip Makey Makey keys and EARTH to your circuits and play games with a drawn controller, jam out with a sketched sampler board, or tell stories with interactive art. All this and more can be accomplished with Makey Makey 6B Conductive Pencils, now sold on their own as a box of 12!
