Perhaps I'm mistaken but doesn't the experiment demonstrated at this link fit the bill?

How about explaining what's happening that verifies inertia and/or gravity, or whatever you think it represents.
The objects are in a near vacuum, so air pressure is not affecting them. When released they fall, in a very predictable manner, to the ground. Some form of force is required to create movement. In this case I believe the force is gravity, pulling the objects towards the ground. We know air pressure has nothing to do with it, no stacking etc.
Now you tell me what you think happened there?
That experiment is a con job and it's plain to see it is.
I can't really give any genuine answer to that video other than to simply say it's clear and utter bullshit designed to skew people's thoughts who argue against gravity and what not.
However, let's imagine that to be a real evacuation chamber that does evacuate a mammoth amount of atmospheric pressure.
The bowling ball and the feather would still fall at different rates. I'm talking about a real feather and not the bullshit one's that are used in that laughable video.
Either way you look at it, that bowling ball starts off under atmospheric sea level conditions, or thereabouts.
It then has to be lifted up by using energy of a crane.
It's still displacing atmosphere as it is lifted up and is still displacing atmosphere as the container is under evacuation of pressure.
It still pushes through the remaining atmosphere that is left, which is much less friction acting against it's push down which will actually make it move quicker but would hardly be noticeable to the human eye.
However, a real feather would fall faster due to it not hitting anywhere near the resistance as it's pushed/squeezed down.
In that crap video you see the feathers not flutter at all. The reason for this is because the video is a scam to make it look like a vacuum is the reason.
The truth is there would be fluttering to be seen all the way down, not just on the very first second of the drop.
Understand what it takes to evacuate a chamber and you'll understand that the near supposed vacuum in this one is ridiculous.
Remember that air isn't pumped out, it's allowed out with the pumps main objective as being a force against atmosphere GETTING in. The pump pushes atmosphere away from the container to allow the container to decompress by molecular expansion, alone.
The video is a scam.
The faces on the bozo's monitoring it tells its own story, along with face for TV, housewives choice, rock start come professor of all Earth sciences that are impossible to verify...Brian Cox.
The old, " wow, look at them, they stayed together."
What? Have they never thought to test this out and require a similar set up to a fake rocket launch consisting of all kinds of computers and jargon in order to drop a frigging ball and feather?
There would be a shit load more experiments done at any one time if this thing was any use in any extreme so called vacuum like environment, as we are told.
There's no proof for gravity or inertia. They simply do not exist and this is the best they can come up with to try and convince the masses.
It works for the masses but not for those who can see past the utter bullshit and is the reason why all kinds of ways and means are being tried to try and keep the masses asleep and to make the awakened one's appear to be lunatics.
Mild soap box stance over.
