1950s B.F. Goodrich Rubber Products Promotions Film by John Sutherland 50884

I know what you're thinking. I've already posted this, right?

Well, sort of.

That already-posted video was 10 1/2 minutes long. This one is almost 17 minutes and contains some extra content. It's sort of like a director's cut versus the original release.

We still get the 'what makes a ball bounce' opening (though the edit misses a line or two) and the horribly offensive 'Japanese' sun at 4:00.

At 6:30, though, we take an entirely new field trip to the artificial rubber lab to see how polymers are made - 'tree rubber', man-made rubber, and Geon. For example, we see vinegar being added to man-made rubber (kind of like our latex/bouncy ball lab in the summer camp) to produce a really messy clump of rubber balls.

The various animations - world war II, the monomers being ordered around by the 'Sargent' catalyst - at 9:00 - and the plasticizer's exaggerated curves at 9:40.

There is a couple of minutes of new content around 11:30 showing off new applications of synthetic rubber (drilling hoses, v-belts (?), lifting cars, insulated rubber boots, swim caps - perfect for smoking by the pool apparently, airplane de-icers, tubeless tires).

But we still close with - in spite of learning 'how to make a plane fly faster than sound...to create new products and materials...even [to] split the atom' -  not knowing what makes a ball bounce.
