The Jumping Flame Trick. In Classroom Activity #95 by Robert J. Eierman, students follow in the footsteps of Michael Faraday and investigate the factors—fuel, air, and heat—that enable a candle flame to burn. The results are used to understand what happens when you blow a candle out. Included are activities that illustrate what is burning (the jumping flame trick), where the heat is generated (the scorched card), and what the wick does. The activity involves students working with matches and lit candles and therefore requires careful supervision.
