At the beginning, a movie “Nikola Tesla - Spirit, Work, Vision” was shown by special permission of the Nikola Tesla Museum in Belgrade. Based on the movie and students’ knowledge about electromagnetism, a discussion was developed in which students actively participated. At the end, experiments with plasma globe were performed. They, in their rudimentary form, were discovered by Nikola Tesla. Students’ interest surpassed our expectations, they participated in the demonstration and the discussion continued after the end of the class, for as long as time permitted.
