Just once, I'd like to verify this experimentally...

Well I probably don’t think of hp as being anything as other than what
non-technical people say. Who knows what work a horse can do nowadays?
If the health and safety or animal welfare people allow it ;)

Of course, it wouldn't be *that* hard to do on earth.

So much for "they did it on a soundstage and slowed it down". :-P

Yeah, because a high vacuum is easy to come by. Oh, wait...

I've seen a demo of this in a few science museums. It's pretty nifty,
but in the vacuum they both fall fast enough that you don't really get
to look at it for long.

Well, yeah, it is. It's called a bell jar.

(Note - the next video after the one I posted.)
You can go to edmond's scientific and buy bottles of vacuum for like a
quarter each, too. It's not like you need interstellar-space vacuum to
prove the point.

You'd need a pretty damned big bell jar to drop an object any
significant distance.

Really?
The London Science Museum has a bell inside a jar with a vacuum pump.
But last I checked, a pump powerful enough to create anything you could
describe as "a vacuum" is an extremely expensive piece of scientific
equipment.

In that, my friend, you are absolutely right.

Somewhat larger than the distance it takes to see a feather and a ball
bearing falling at different speeds in atmosphere.

Yes. Ever get blood drawn? How do you think that works?

Even the $25 pump gets you down to 29" of vacuum.

Presumably they just use a syringe. I wasn't looking at the time; I was
in far too much pain...

Interesting. I wonder what it costs to buy a large container than can
withstand several thousand Newtons of force trying to crush it...
