The thing that stops me about this event is I don't understand what the educational point of the exercise was. I presume that the idea was demonstrate the technical point that not all chemicals burn at the same temperature, but is that message delivered by this exercise? I guess the cultural lesson that might be imparted is that magicians have a scientific basis for their illusions. This could potentially arouse some junior high students' interest in learning science, but I see a high risk of misuse or misinterpretation of this lesson by students of that age.
What is the upside of this demonstration besides the fact that social media delivers a convenient video of the demonstration to anyone who poses a semi-related search inquiry?
