Query: Helical Blowout Jets in the Sun: Untwisting and Propagation of Waves   We report on numerical experiment of the recurrent onset of helical "blowout"
jets in an emerging flux region (EFR). We find that these jets are running with
velocities of $\sim 100-250\,\mathrm{kms^{-1}}$ and they transfer a vast amount
of heavy plasma into the outer solar atmosphere. During their emission, they
undergo an untwisting motion as a result of reconnection between the twisted
emerging and the non-twisted pre-existing magnetic field in the solar
atmosphere. For the first time in the context of blowout jets, we provide a
direct evidence that their untwisting motion is associated with the propagation
of torsional Alfv\'en waves in the corona.
