A new $30 lens extension will allow you to see the unseen with your iPhone's camera.
Granted that this works with iPhones, this will work with any smartphone that has a camera. All thanks to UC-Davis researchers, we now have a 1 millimeter ball lens that is mounted with rubber capable of being attached to any smartphone camera. The lens gives your iPhone the power of a 350X microscope. The lens is taped onto your iPhone's camera and the whole bundle only costs around $30. Won't it be worth it to get a kick out of scaring your kids by showing them just what kind of a filthy world that they live in?
