Science!

[ADDED]

If you went to school in the 60s and 70s, you almost certainly heard this guy’s voice telling you about the wonders of magnesium oxide, maybe with a slight tremble caused by a short loop that made the audio track in the 16mm film jump as it rattled through the projector.

That, and the way most of the technological jargon almost, but not quite sounds real (“prefabulated amulite” is one of my favorites, for some reason I can’t quite pin down) until he throws in a “dingle arm” or “girdle spring” that trips up my brain and makes me think, Wait a minute, that can’t be right!

For a little background on the turbo encabulator, this wikipedia article summarizes its development nicelly. I found this updated version with modern science video narrator Mike Kraft, after reading an interview he gave to a technical journal.

[ADDED AGAIN] There’s made-up technojargon that sounds real, and there’s real technojargon that sounds like it’s made up: “Martian spherules are the abundant spherical hematite inclusions discovered at Meridiani Planum on the planet Mars. They are found in situ embedded in a sulfate salt evaporitic matrix, and also loose on the surface.” (from a Wikipedia article on Martian spherules)
