In my opinion, it's the same kind of science as used to justify Foucalt pendulums. Just bunk. The dudes at least admitted the effect is negligible, which is true. Emptying water is going to have to spin one way or another. A slight tweak to the experimental apparatus will achieve whichever direction is preferred. The result has nothing to do with proving heliocentric theory. If anything, it probably disproves heliocentricity, because spinning water would probably be readily observed as is predicted by heliocentric theory.
Well, the important thing is that we do not speak/push falsehood with the name of Christ/Christianity. I'm sure you agree the order must be 1. Christ, 2. no falsehood, 3. my desire that FE/SE be true and/or my desire to spread FE/SE.
The experiment is what you asked for, but I think you'd admit, you didn't want it. Why are bringing heliocentrism into this? I didn't associate the two. This is a proof of the Coriolis effect, and another SE proof. The sun can revolve around the earth and the Coriolis effect would remain the same.
I can tell you've just looked for things that support FE, cause that's what you want. That's not seeking the reality of this issue, is it? If want to discover if SE or FE is the reality, you need to look into the preponderance of evidence for both (& view/do experiment when applicable), not just for one. The first step is understanding the concept and seeing what proofs there are, yes?
The Coriolis effect is what happens due to the earth spinning on its axis; and every degree/latitude higher/lower than the equator moves less distance per rotation. Degrees-wise, the equator is zero, the poles 90/-90.
This is the best 2:40min vid I've seen that displays the physical mechanisms of why storms spin counterclockwise in Northern Hemisphere and clockwise in Southern.
The Coriolis Effect Explained - YouTube
This (real life, nonanimated) vid demonstrates the Coriolis effect with a spinning plate and marble. The marble will travel straight across the plate when not spinning, but angles when plate is spinning. Proof of concept. 0-2:32min covers it. There are many more examples on youtube.

This (real life, nonanimated) vid is great too. If two people are on a long plank and throw a ball directly at each other the ball will reach the other person. But when they're spun, it will not due to the Coriolis effect. There are many more examples on youtube.

In regard to the spherical earth spinning, with ballistics the Coriolis effect can be more easily observed/measured when measuring a sufficient distance. It can be predicted, calculated and confirmed with hands-on experimentation. Obviously, the results are directly dependent to where you are on the earth and what direction you are shooting. In the below vid a long-distance rifle shooter demonstrates the Coriolis effect by first shooting due east and then due west. You can do this experiment yourself.

Let's move to evidence of both curvature and Coriolis effect in calculation charts in both naval ordnance and artillery manuals. This only came into effect when distances increased beyond visual range. (Below that I will post a couple vids that reference, corroborate and discuss manuals and use.)
Halfway down the web page we see the scanned pages referencing the tables with "rotation of the earth" (

Finally, these two vids below reference, corroborate, discuss manuals for Coriolis and curvature. Naval ships 1st vid. Land artillery included in 2nd vid.
