A symmetric harnessed gyroscope accelerated to a given spinning frequency takes different time periods to stop, depending on the direction of previous spins. For repeated alternating, anticlockwise and clockwise spinning, the rotation period in both directions significantly increases, which is not the case when the gyroscope is repeatedly rotated in the same direction. Using the measurements it was observed, that the time of gyroscope's rotation was significantly lengthened or shortened, what indicates that it either increased or decreased the movement resistance of the gyroscope. The presented experimental results suggest the existence of anomalous movement resistance and demonstrate that a fixed spinning gyroscope displays unusual history-dependent movement resistance effects. The effect is real, large, reproducible and does not follow from experimental errors.
