CIS Students learnt about the functioning of a bulb and the simple science behind one of the greatest inventions made by mankind

Can you imagine what life was like before you could simply flip a switch and turn on a light? 
How would not having electric light affect the way you live your life? In the 1870s, many inventors were working on creating lighting devices, but until Edison became involved, what existed was electric arc lighting. On December 31, 1879, after years of work and thousands of experiments, Edison gave the first public demonstration of the incandescent light bulb at his laboratory in Menlo Park, New Jersey. Students of Big Bang Squad learnt about the functioning of a bulb and the simple science behind one of the greatest inventions made by mankind.
