Shadows are created when light passed through an opaque object. Shadow is darker when the object is more opaque and is lighter when the object is translucent. It is hardly visible when the light passed through a transparent object.
The shadow becomes bigger and blur it it is far from the light source but becomes smaller and more distinct when it is nearer to the light.
We had a great time discovering all these through our shadow play and even created a storyline
to go along with our props.
