There was no magic in any of the materials used for Gemini and Apollo either,
but countelss things were learned just by using them out there.

Care to name a few specifically from Genini and Apollo?

And BTW, 99.9% of the materials used is aluminum.

Much of the medical monitoring technology came out of the early space
program, for one thing. So did advances in propulsion systems and
remote controls (more than just model planes and cars) for another.

True, but none of that came from throwing the stuff up into space just
to see what would happen.

No, but they all came from the space race (Mercury, Gemini and Apollo
programs) - which was your question.

Nope, my question was what came from throwing the stuff up into space just
to see what would happen.

Perhaps I should have phrased it more clearly.

And since then, there have been all kinds of experiments on various
orbiting objects such as MIR, Skylab, the space shuttle and ISS. Many
discoveries are coming out of it - although I don't know offhand what's
been put to use yet, since there is no manufacturing in space. But
thinks like perfectly round ball bearings and new ways to make
pharmaceuticals come to mind.

All of which revolve around the concept of doing something dynamic
in a zero gravity environment. None of it has anything to do with
some material showing some new and hitherto unknown property simply
by being in such an environment.

Take ball bearings for example. It has long been known that absent an
external force, i.e. gravity, that a liquid will form into a sphere
due to surface tension.
