Aron J. Ihde, 60 years ago, did experiments that also were spectacular.  But the set up was intellectual and required first developing in the students an understanding of the chemical principles that would be illustrated.  The safety was also a part of the presentation which was done at a distance from the audience with full gear and a trained assistant.  The excitement in that lecture hall was not generated by jumping around and audience participation, but by the excitement each of us felt when we saw a physical manifestation to reinforce the chemical principles we had just learned.

Those students in the video are too young to appreciate anything but the antics.  And they will be tempted to do similar "experiments" on their own.
