Popis:	We have studied the dynamics of a superfluid helium-4 meniscus on a solid substrate. In a pseudo–non-wetting situation, there is no hysteresis of the contact angle. We show that distortions of a liquid meniscus do propagate along the contact line. We have analyzed the propagation of pulses. We find a good agreement with theoretical predictions by Brochard for the dispersion relation of oscillation modes of the contact line.
