This 16mm reel has lost all its color, but what a document it is of a time when spending all day hovering over open beakers of ether and acetone (or mixing them together - even better) was just fine. You'd come-to eating a sandwich in a strange place having no idea how you got there or what it was you'd been doing all day. Oh, those free-wheeling days of science! Enjoy!

    The color washout is identical to the 35mm slides I have of the Viet Nam war.

    And you can really fill the room with acetone vapour if you add a nice paper wick to the bucket :o)
    Nice to see though Fran, inspite of 1960s lab standards…
    Metric units used for length measurements in 1961 in the US – hurrah !

    We just threw science on the wall and saw what sticked. Haha. We do what we must, because we can.
    It's a very interesting and pretty in-depth material on a narrow subject. Different techniques and all that.
    I remember doing some experiments with paper chromatography, but on a smaller scale (test tube rather than beaker). It was probably some plant material transferred directly from the leaf to paper, and I think I used rubbing alcohol as a solvent.

    Interesting mix of inches and centimetres !

    Fran, I see what you mean. I just "woke up" after watching all 14 1/2 minutes of this film and have no idea what I was watching… but it was fascinating.
