You can use a mechanical gyroscope to measure rotation if its large enough. Laser gyroscopes are far more accurate and smaller, which is why they are popular today.
Mechanical gyroscopes
For an observer at the surface of the Earth, the Coriolis force would be responsible of moving the gyroscope axis of rotation. It is well-known that this force is weak on small system, by which I mean it is easily overwhelmed by non-inertial forces such as friction, viscosity, etc. This is why Foucault pendulums have to be sizeable (the smallest I am aware of has a string about 5 meters long). Thus I reckon you would need a gyroscope way bigger than the mass-produced ones. I am not aware of any purpose-built gyroscope to test Coriolis forces. But why would anybody bother when it is so much easier to build a Foucault pendulum?
But it goes into what I said in my first post, you cant debate a flat earther because yall dont believe shyt, cant actually prove the earth is flat but dont care cause yall believe the burden of proof isnt on yall.
By that EXACT SAME "coriolis effect", it's "scientific fact" that a person should be able to hover in a helicopter and have their destination on the ground rotate to them if they wait long enough. Have you observed this ever?
ALSO, by the EXACT SAME "coriolis effect" a westward flying plane flying ~500 mph at the equator SHOULD reach the exact opposite side of the earth in less than 17 hours, while an EASTWARD flying plane moving at 500mph at the equator going to the same spot SHOULD NEVER REACH IT'S DESTINATION, being that the earth supposedly rotates ~1000 mph east, which is a GREATER SPEED than the average plane can travel PERIOD
This is a fact due to the CORIOLIS EFFECT(a concept of heliocentric theory) that dictates that once an object leaves the ground on the earth, that object IS NOT TRAVELING AT THE SAME SPEED AS THE EARTH'S ROTATION, meaning that the earth's ROTATION has to be accounted for with respect to ANYTHING traveling in the air

Coriolis force; plural noun:
Coriolis forces
- an effect whereby a mass moving in a rotating system experiences a force (the Coriolis force ) acting perpendicular to the direction of motion and to the axis of rotation. On the earth, the effect tends to deflect moving objects to the right in the northern hemisphere and to the left in the southern and is important in the formation of cyclonic weather systems.
In physics, the Coriolis force is an inertial or fictitious force that seems to act on objects that are in motion within a frame of reference that rotates with respect to an inertial frame. In a reference frame with clockwise rotation, the force acts to the left of the motion of the object

Also, I asked for a real life example of a mechanical gyroscope proving that the earth is a rotating spheroid and you just googled a definition and posted words
