Significant questions regarding turbulence in quantum fluids, such 
as superfluid helium, remain unanswered owing to the inability to 
directly probe the local velocity in a manner quite common in the study 
of classical fluid turbulence.  Using a novel visualization technique to 
measure the local velocity field, we  are able to characterize 
fundamental processes in turbulent superfluid helium. A mixture of 
hydrogen and helium gas is directly injected into the bulk of the fluid, 
which produces micron-sized tracer particles that are individually 
tracked.  We demonstrate the two-fluid nature of superfluid helium and 
make the first observation of  individual reconnection events, and we 
compare the local velocity statistics with predictions for turbulent 
quantum fluids.
