Answer the following questions:
  
1Would you like to become invisible? What advantages and disadvantages do you foresee, if you did?
 
2Are there forces around us that are invisible, for example, magnetism? Are there aspects of matter that are ‘invisible’ or not visible to the naked eye? What would the world be like if you could see such forces or such aspects of matter?
 
3. 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!)
