Mirror Half Reflection Optical Illusion
| This mirror optical illusion is very easily accomplished. All you have to do is find a mirror big enough, and place a camera (you don't really need the camera unless you want to record the optical illusion)on one side of the mirror in such a way that the camera's lens slightly inclined looking from one side of the mirror towards the other end. Ask somebody to stand on the other end and watch the optical illusion. If this explanation makes it seem harder than it looks, just get a mirror, get a second person to help you and you will find out the trick without need for instructions. The kids in this video had endless hours of fun out of this mirror. |
