The evolution and dynamics of solar chromospheric structures (e.g., spicules, fibrils) may be key to understanding mass and energy transfer from the lower solar atmosphere up into the corona. Because of their thin, long, jet-like appearance, it is observationally extremely challenging to deduce their true motions and associated wave physics. The research presented provides a revolutionary insight into the fine-scale time/space plasma evolution of coupled transverse and torsional motions in spicules. Further, by exploiting the highest spatial/temporal resolution Hα imaging spectroscopy data available from the CRisp Imaging SpectroPolarimeter (CRISP) based at the Swedish Solar Telescope (SST), we describe an innovative technique, which for the first time, reconstructs 3D velocity fields for spicules. This will allow us to make a great step forward in understanding their dynamics and ultimate contribution to energy flux transfer between the lower and upper atmosphere.
