When I was in school, I used to love whenever there was a film to be watched. For one thing, it meant less lesson time, as setup of the film equipment would take time; then it was usually amusing to watch the stuff.
Most of the time, these films were already quite old, dating back to the 70s or even 60s. So these educational clips had their own peculiar charm - and I'm very much reminded of these by the films in the TIB.
The TIB is the information portal of the Leibniz Information Centre for Science and Technology, and you can find a video collection there, among a lot of other resources. Which, for instance, includes this gem:
I haven't figured out what the woman spinning the tow does with that circular hand motion, but in one of the shots you can see a lot of debris on her skirt, so maybe it's trying to take out the debris? Towards the end, there's a very quick bit of distaff dressing as a bonus, one of the many, many different ways to get flax ready for spinning.
It's a lovely little film in any way, and I hope you enjoy it as much as I did!
