We present experiments on nematic aerogel oscillating in superfluid ³He. This aerogel consists of nearly parallel mullite strands and is attached to a vibrating wire moving along the direction of the strands. Previous nuclear magnetic resonance experiments in ³He confined in similar aerogel sample have shown that the superfluid transition of ³He in aerogel occurs into the polar phase and the transition temperature (T_ca) is only slightly suppressed with respect to the superfluid transition temperature of bulk ³He. In present experiments we observed a change in resonant properties of the vibrating wire at T = T_ca and found that below T_ca an additional resonance mode is excited which is coupled to the main resonance.
