Twisters in Love

If we make one of the windmills rotate, the other will also start rotating. After a few rotations one of them might stop, but it is started off almost immediately by the other one. If the first one rotates too fast, the other is at a standstill, dithering, not knowing which way to rotate.

There are magnets in the sails of the rotors, with the same poles facing the outside. The sails repel each other. The rotation of the rotors is chaotic, as a result of changing position of the rotors.

The movements of the windmills resemble the behaviour of a pair of lovers. Sometimes they sand facing each other and sometimes they turn their backs on each other.
