Let's see what is afterimage???
Materials:
3X5 Note card
Tape
Pencil
Scissors
Colored pens
Cut the note card into half.
On one piece, draw a bird right in the middle of the card.
On the other price draw a cage
in the middle of the card.
Tape the cards back to back on the end of a pencil so that you can only see one image at one side.
Rub the pencil very fast in your hand and you will be confused to tell if the bird was inside the cage or outside???
The effect is known as afterimage. This is a ability of our eye to see the images even after they are gone!! This is ability is know as afterimage!! When you spin the pencil you see the bird first than you rotate it very fast while you are seeing the bird the cage comes in focus and for this reason you think that the bird is in the cage!!!!!
