Popis: | We describe experiments in which a sound pulse is used to inject small particles into liquid helium at temperatures between 1 and 3 K. The motion of these particles is then observed. We are able to observe the effect of applying an impulse to a particle that is attached to a vortex. We also report on a number of surprising motions of particles and discuss possible explanations. |
