Experiment with gravity and inertia.

This experience is not something new in physics. It has long been tried this kind of curiosities in the field of physics to apply in many interesting technical solutions but so far without significant success. The cone seems to contradict gravity, because it moves along an evenly sloping hill. In reality, however, it falls, and more specifically, the center of gravity in the middle position is lower than in the initial position, so despite falling slope, it can move uphill instead of falling, in fact it falls by performing upwards displacement.

Composed as inclined so that the cone would fall from the highest place to the lowest.

It can also be arranged centrally.
