Before Chester Carlson invented photocopying, inventors engineered various mechanical devices to replicate images. With a few everyday items found in the home, you can make a pantograph, an image duplicator that allows you to use one pencil to trace an image while another pencil follows its path in parallel to produce a near-identical copy.
