Manu Prakash, a bioengineer at Stanford University, has created a fully functional microscope out of waterproof paper that uses teeny tiny lenses to magnify objects. He calls it a Foldscope. The different parts of the microscope are printed on paper, which the user punches out and folds together. The Foldscope requires no power outlets and works with standard microscope slides. The Foldscope operates a lot like a traditional microscope in that it uses lenses to bend light in order to make tiny images appear larger. Watch the video to learn more.
