Question:

What makes glass or water transparent (what is the scientific explanation for this)? Do you think it would be scientifically possible for a man to become invisible, or transparent? (Keep in mind that writers of science fiction have often turned out to be prophetic in their imagination)

Answer:

The fact that light can pass through glass or water makes them transparent. When light falls on an object, the reflected light from that object makes it visible to us. If some device can be made which can prevent reflection of light from the human body then the human body can be made invisible.
