Student generally observe dielectric breakdown of air during thunderstorm in the form of cloud to cloud and cloud to ground lightning bolts. Same can be realized in the classroom or laboratory experiment with the help of electronic waste of old cathode ray tube TV set. This paper demonstrates the usefulness of electronic waste to demonstrate multiple physics concepts to secondary and higher secondary students.
