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.
