Description: |
|
A system of concave mirrors produces images of objects placed inside it as if they were sitting on top of the device. Aim a narrow beam of light from a penlight or laser at the image. The spot on the image where you aimed the light is illuminated. The Mirage optical illusion is a perfect reflection and refraction demonstration for your classroom and it's even cool enough to amaze your friends at home. This unique device consists of two 23cm diameter curved sections, black on the outside and mirrored on the inside. When you place an object inside The Mirage directly below the hole in the upper section, the object "appears" in the hole. Your students will be amazed when they try to grasp an object that's not really there! |
