One of my favorite physics party tricks —taught to me by physicist Michael Faraday—is to gently blow out a candle and then quickly reignite it by lighting the “smoke” trail and watching the flame travel down to the wick. I have purchased and given away several Dover edition copies of Faraday’s short book The Chemical History of A Candle, taken from his Royal Society Christmas Lectures for youth of 150 years ago, illustrating the powers of scientific observation and scientific reasoning examining the chemical, physical, and even biological processes and equilibria displayed within the combustion of an everyday candle. Unfortunately, online versions of this work usually lack his illustrations (and brevity), but Bill Hammack (the Engineer Guy) and colleagues have taken up modernizing Faraday’s work as a project, producing an updated edition of the book, elementary though middle school-pitched student investigation worksheets, a teachers’ guide, and six...
