Principle explanation:
After the motor is powered on, it rotates to drive the top two magnets to rotate equally. After the magnets reach a certain degree of rotation, a magnetic eddy current is formed, and the metal egg on top will rotate with the magnetic eddy current. The rotation principle is to rotate along the long axis, accelerate the rotation, and finally form a gyroscopic effect. The metal egg/mushroom will stand up.
