I am not in "education" but have conducted a lot of training in the military and industry in trying to demonstrate to individuals how and what you must do to
avoid getting killed, injured or ill. Regardless of the age of the student, lecture just doesn't cut it by itself, and I agree "live" demonstrations have and will have tragic results not only for the students for the instructor. There is such a wealth of good
internet information, using that and a little imagination you should be able to get most of their attention and get the message across, and be safe.
I find chemistry, especially that related to industrial safety, fascinating but I can easily find YouTube or other materials that show the aftermath of poor decisions
or incompetence without harming anyone. One doesn't need to get exposed to nerve gas to determine "what is that like" after I showed my men the training films developed by the Army, but did have trouble getting individuals to "respect" the training kits of
the 1970's for testing for chemical warfare agents. Some got really sick and hospitalized - just wouldn't listen. Same problem I have with chemicals in manufacturing - how do you convince individuals to take proper precautions to avoid lung disease when the
materials are tasteless, odorless and feels like gritty talcum powder? I show them slides of lungs effected by silicosis. Of course they then take a "smoke break".
Please keep trying - your students of today are my employees of the future! Thanks for your continuing efforts!

I have been asked, more than once, why I did not do more "exciting" demos or labs. I believe labs are a learning experience and not for entertainment. I have heard many teacher talk about feeling the need to entertain their students with
demos to engage them in learning. It seems to me, there is a culture of doing demos for the effect and not the learning. This needs to change.

What is as disturbing to me as the risk this guy is in and his students, but the comment by 'empowermind.co.uk': "Cool video! I like watching science demonstrations! Thanks for posting and keeping chemistry real for the next generation!" Is chemistry only 'real' when it explodes?
Just a rhetorical question.

Here's a new one on me. Science teacher uses "explosives," according to
the title, or "flammable gas" according to his narrative, to carve a
pumpkin. I'm guessing methanol, based on the video? No shields, lots of
flame.
