We present a statistical study of spectral images, taken from the CRISP instrument at the Swedish 1-m Solar Telescope in H-alpha 656.28 nm of high-speed spicules with Doppler velocities in the range of -41km/s to +41 km/s. Remarkably, many of these spicules display apparent velocities above 500 km/s, very short lifetimes of up to 20 s combined with width or thickness of 100 km and lengths of around 3500 km. We observed transverse motion associated with these structures which in some cases could be related to high-frequency kink-waves, high-frequency torsional Alfvén waves or high-frequency helical kink waves. We also observe examples of multiple-MHD modes present when these features interact. Also, we show simulations that represent evolution and propagation of these waves from the photosphere to the lower corona. These waves carry enough mass and energy to contribute to towards the energy budget of the corona.
