This is the video we will discus about:
The photos explaining the experiment can be seen here:

Images are showing how the inclination after 17 minutes haven't changed at ALL(I showed with blue lines the lenses distortion for the ones who think the gyroscope starts spinning inclined since the beginning. Anyway, the change in inclination matters and there is no change in the inclination)(the gyroscope should have not problem to stay inclined because it is a gyroscope. But it is not inclining...).
This, plus this pendulum:
...is proving to me that the earth is planar and it rotates in a way like shown in this GIF:

This experiment should give the most clear results at the equator. And this experiment does not require people to travel. Because it is about degrees, sayings like "Earth is too big to notice it" are not valid.
Please, if you think I am wrong, feel free to disprove my proposal. I want proofs and want to find the truth.
An interesting and unique take... I have never heard of and FE model that rotates. Amazing.
The Foucault pendulum question... try the same pendulum in different parts of the world. If the world is flat and rotating as you suggest, then all pendulums should rotate in the same direction at the same rate. Is this true or not? Research the answer to that and get back to us.
The spinning top question... This one is very interesting. If this test was done at the equator, we would expect have experienced 4 degrees of rotation around the horizontal axis during this video. What would that look like? As it turns out, this is not an easy question to answer. If we simply tilted the plate, the top would stay upright, but we didn't do that... we tilted the gravity vector too. What would that do to a spinning top? The answer is pretty complex. Graduate-level physics complex. Let's think about it in the context of our understanding of tops.
If you start a top at a very tiny incline (not perfectly straight up and down), what does it do? Look at @0:05... the guy places the top down by hand, so it won't be perfectly aligned. Take a screenshot and see if you can estimate about what angle he drops it at. What we have here is an example of how a top responds to a slight misalignment between the gravity vector and its upright.
a) The first thing I notice is that it starts moving in circles.
b) The next thing I notice is that it quickly rights itself.
c) As we continue to watch, we see that the circles gradually decrease, and the vertical alignment of the top gradually straightens.
This is all consistent with my own experience with tops. From this, what can we say for certain? Well, we aren't sure of the physics behind it, but we have observed that a spinning top will right itself if the angle is tilted. Let's apply that to a rotating gravity field and see what we think should happen...
When the gravity field rotates, the top will get out of alignment. This is precisely analogous to when the guy dropped it in the beginning. We would expect the top to start going in a little circle while it rights itself. Is that what we saw?
How much does the gravity field rotate? 4 degrees over the course of 16 minutes. The gravity field is rotating slow and steady, so any adjustments the top makes are also slow and steady.
So to sum it up, what we see with this experiment is consistent with what we probably should expect. Tops DO right themselves. If they didn't, kids would never be able to make them work. The physics is certainly not obvious nor trivial, but tops work. This we know for sure.
