The Foldscope is a portable and versatile microscope made mostly out of paper (water-proof) that magnifies the wonders of the microscopic world, without the bulk and expense of a conventional research microscope. Foldscope is designed to bring microscopy out of science laboratories and into the hands of people around the world. And it costs less than a dollar!
