Fonctionnement - A glass to see in reverse

  • The lower part of the image, seen through the water, should be reversed.

     

    If the image is not very sharp or not reversed, move the glass forward or backward a little and also move back until the effect is clearly visible.

     

    Depending on the shape of the glass and your position, the image may also be enlarged or reduced or simply very distorted.

     

    Why not create lots of drawings and texts to impress your friends.

     


  • Here is a video showing this optical illusion.
