Playing with the Coriolis force. A rotating merry-go-round is a helpful demonstration of the fictitious force that appears to act on objects moving within a rotating reference frame, such as the Earth.

Simple demonstration of the Coriolis force.

The coriolis force is not fictitious and can be described mathematically

"fictitious force" fic·ti·tious adjective not real or true, being imaginary or having been fabricated.

The Coriolis force was first predicted by Jesuit Priest Giovanni Battista Riccioli in his Almagestum Novum (1651)

For years I thought the whole toilet flushes in Australia thing was a joke. Then I saw a toilet flush in Australia and it blew my mind.

Absolutely, using a rotating merry-go-round to demonstrate the Coriolis force is an effective and practical way to illustrate this concept. As objects move along the spinning platform, observers on the merry-go-round perceive a deflection in the apparent path of the objects due to the Coriolis force. This helps to convey the influence of the Earth's rotation on phenomena like wind patterns and ocean currents on a larger scale.

Well... people who shoot "intuitively" get this. You aim at where your pigeon is going to be, not where it is when you pull the trigger. Same thing releasing an arrow from horseback; both your motion & target motion must be factored. Granted, moving faster than balls, but same.

This “fictitious force” that is centrifugal-force, is also known – according to Einsteinian general relativity, a.k.a. the modern “law of gravity” – as _gravity_.

A Space "Carousel": All About the CF-18 Centrifuge When people hear the word "centrifuge," many immediately picture a playground merry-go-round. However, the CF-18 is not an amusement park ride, but a training device that prepares cosmonauts for spaceflight. ▶️ The CF-18’s purpose is to simulate—here on Earth—the G-forces a person will encounter in space, such as during a spacecraft's launch into orbit and its descent back to Earth. However, G-forces in space vary; the direction of the force differs depending on whether the craft is accelerating or decelerating. Therefore, simply spinning the cabin around a single axis is not enough. How It Works Its key feature is a long radius of rotation (18 meters). This is no accident: at such a distance, the effect of Coriolis acceleration on the vestibular system is minimized. The occupant stops feeling the rotation itself and perceives the load as if moving in a straight line—exactly as they would during an actual spaceflight. A Complex, Multi-Component Design It consists of an 18-meter-long steel arm with a tubular structure; at the end of the arm sits a pressurized, two-seat cabin equipped with special seats for conducting training sessions and experiments. The cabin is attached to the arm via a gimbal mount—comprising a "yoke" and a "ring"—which allows for the precise setting and tracking of the required G-force vector direction. Capabilities The CF-18 can not only generate G-forces (up to 30g, though cosmonaut training typically involves up to 8g) but also alter the cabin's internal microclimate: adjusting pressure, temperature, humidity, and even air composition. This enables the simulation of various stages of a flight. Throughout the training session, the occupant's physical condition is continuously monitored by medical personnel.
