Abstract: | Oscillating objects such as discs, piles of discs, spheres, grids and wires have been widely used in cryogenic fluid dynamics
and in quantum fluids research since the discovery of superfluidity. A new addition are quartz tuning forks, commercially
available frequency standards. We review their use as thermometers, pressure- and viscometers as well as their potential as
generators and detectors of cavitation and turbulence in viscous and superfluid He liquids.
