I teach chemistry and we got rid of about 6 of these a few years back, they were scrapped 
What chemistry vids you looking at doing or what are your plans for the hood?
I feel like there's a gap on the internet between 'fun' chemistry videos, like what Nottingham University produces with their Periodic Video series, and then very dry recorded lectures and people showing organic syntheses. By that I mean there's no real videos that teach chemistry to about A level and beyond that are also somewhat entertaining to people with a passing interest in chemistry. On top of that it's been bothering me that I'm slowly forgetting all the stuff I learned in university, for lack of using it, and it's also been my dream to try make analytical devices like an FT-IR spectrometer. So i'm really trying to combine the two (plus the sillier desire to build props and effects) into a single video, which I believe could turn out fairly decent if I do it right. Although for this video i'm sort of probing the idea by clumsily building a fume hood and covering the 'basics' of chemistry; mostly the stuff I think is most useful, aimed at people who probably don't know a whole lot about chemistry.
I'm still working out exactly what basics I want to cover since there's alot of stuff I could leave for later videos, and it's tricky to know what the audience already knows. I think they call it the 'curse of knowledge'. George Bernard Shaw was wrong; being able to teach is a real admirable skill.
As for the hood itself, I think it's going to be mostly for show. The reactions I plan to do will be for the sake of demonstrating principles, and hopefully stay clear of anything particularly dangerous.
I met a guy a few months ago who was talking about melting beer cans in his back yard after seeing one of the many youtube videos about exactly that, but he didn't seem to know anything about the dangers involved. I advised him against it, but it got me concerned over how irresponsible those videos tend to be. They're often presented in a way that suggests it's a safe thing anyone could try, with the presenter wearing shorts and trainers and acting generally careless. But if the presenter strolled out in a full kiln suit then most viewers would probably get the vibe that it's a dangerous thing to do (or that they want to show off their cool ppe). So in the same line of thought, I think a fume hood would work in a similar way. Nobody pays attention to disclaimers and warnings, but if they see me taking all the precautions I can then they'll hopefully get the idea that it's not something to be taken lightly.
plus I don't want to gas myself
