To become invisible, an object must do two things: it must be able to bend light around itself, so that it casts no shadow, and it must produce no reflection.
Can science make things invisible?
Scientists have found a way to make solid objects ‘invisible’ in a strange way โ by having light waves pass through opaque materials as if they were not there at all. The reason that objects are visible are because of the scattering of light waves, bouncing from a light source onto an item and then into the human eye.
