Is that a film strip? I hate the smell of those. Boiling hot little projector always gave off a burning smell
And is the other thing a lithograph or mimeograph printer or whatever? Don’t remember those other than in fast times at ridgemont high where the kids all sniffed the fresh ink on their handout. Little high can be had there apparently
First picture is of an opaque projector. It uses a very high wattage incandescent bulb and projects the reflected light.
Second pic was mimeograph. Organic solvent based copy fluid gave off the most bizarre smell. If the teacher came in with freshly printed material, it would still be a little damp and you could almost see the smell coming off of it…
My physics prof in university used an overhead projector but those smelling copies stopped when I was in grade 6 or 7. And yes, that smell was quite distinct. We’d all take huge whiffs of fresh copies
Description of video does say it was "custom straight pipe exhaust (not sure if you were making fun of clochner or being serious). Does sound damn good though.
