When light falls on an opaque object, light is obstructed, and a dark patch on a screen kept behind is called
shadow. Or the light rays that go past the edges of the material outline the shadow. Hand shadow puppets
are easy to do, are lots of fun, and can be created just about anywhere.
Make your own hand shadow puppets on a wall by using a light source (like a torch or a lamp). (A bedside
lamp or table lamp works perfectly.)
Put one hand between the light and the wall, so that you can clearly see the shadow of your hand.
Some examples of hand shadow puppets are given below.
