Persistence of visionrefers to the fact that light's stimulus lingers on the retina slightly longer than it actually shines on the eye.
Supplies needed:
- Round piece of cardboard
- A hole punch
- Twine /string
- Scissors
- Paper
- Pen/ Pencil
- Tape/Glue Stick
- Think of an image you want to trick your eye into seeing. In the above case it is a bird in a cage.
- Take two pieces of paper and cut them down to a size where when glued or taped it will fit within the boundaries of your cardboard piece.
- On one piece of paper draw a bird. On the second piece draw an empty cage. If you have your own image ideas draw them instead.
- Take your cardboard piece and your drawing of the cage. Center your drawing on the cardboard piece and glue or tape it down.
- Flip over your cardboard piece and repeat step 4 but with the image of your bird.
- Now take your hole punch and make holes opposite each other on the cardboard piece. There should be only two holes when you are done. Refer to the picture above.
- Cut two pieces of twine/string making sure they are close to equal in length
- Take one of the pieces and tie it through the hole you punched. Do the same with the other piece of string and other hole.
- Hold on to the pieces of string and wind up the cardboard piece. Once wound up loosen your grasp, so that it starts to spin. Your eye will now see only one combined image.
