Another classic Bell Labs film from my collection, this one released in 1970 but with footage from a couple years previous, it is chuck full of laboratory experiments and overflowing with science! A very enjoyable 16mm film that I certainly saw in school back in the day. As usual I transferred this film with my own Telecine and used some minor color correction. Enjoy!

    What?

    Not only is this one of my favorite scientific subjects (kinda goes hand in hand with audio engineering), but this is RIPE for riffing. I think I may just write and record my own commentary track.

    Great film again. I wonder if it's possible to get access to school films like this here in Germany nowadays.. I will check out, since I have a german "Filmvorfรผhrschein" for playback of these 16mm-films on Bosch-Bauer P7 or Siemens 2000 since 1983..maybe the staff didn't even know of that stuff.. ๐Ÿ˜

    I hadn't considered that street noise of traffic and people could reach dangerous volume levels until you mentioned you used to wear earplugs for the subway in New York… that was a surprise. Such an interesting documentary, thanks for sharing.

    Flames conducting sounds? Think of the hi-fi equipment!

    The phrase, "listen to the science" comes to mind as well…

    Two jobs ago, I saw a demo of the flame speaker at a science display. As I recall, a bottle of some type of salt in water, a high voltage transformer, Bunsen burner and a fairly high wattage vacuum tube amplifier.
    I used to live in a semi rural area, and you could hear things at surprising distances…
