It's episode number 10, and this is a very special topic. The Bunsen burner is emblematic of this podcast and of science itself. But did you know, that the simple redesign of this gas burner opened up the field of chemical spectroscopy? Join us as we explore the career of Robert Bunsen, a beloved teacher who survived arsenic poisoning and explored the geysers in Iceland and finally created the much renowned burner.  Also we tell you how Jonah made his own type of burner and what sound electrons make when they get excited.
