Materials Required:
l Paper towel tube
l Matchbook
Procedure:
To discover a power that you are probably not aware of, try this easy experiment. Did you know that your eyes can pierce solid objects?
- Hold an empty paper towel tube in front of one eye. Hold a matchbook in front of the other eye, with the cardboard touching both the tip of your nose and the tube.
- Look straight ahead while keeping both eyes open. Your eyes have just burned a hole through the matchbook!
This Is What Happens:
You use both your eyes to see an object. Your brain receives a message from each eye and combines them for the total picture. Usually the messages are the same because both eyes are looking at the same thing. In this experiment, however, each eye sees a different image: One eye sees the matchbook and the other sees the view beyond it. The brain combines these and it seems as if you are looking right through the matchbook.
