contents Bunches of swaying and spinning plasma jets in the solar atmosphere - the spicules - exhibit a variety of complex dynamics that are clearly observed in the images of the solar limb. Utilizing three-dimensional radiative magnetohydrodynamics (rMHD) simulation data, we uncover another facet of a forest of spicules that turns out to be a manifestation of the two-dimensional plasma drapery, instead of one-dimensional conical spikes. This fluted morphology is observed in other contexts like molecular clouds, auroras, and coronal loops. Further, using a sequence of high-cadence line-of-sight integrated images, generated from our simulation, we obtain multiple episodes of spinning amongst clusters of synthetic spicules, also reported in observations near the solar limb. This perception of rotation, according to our findings, is associated with hot swirling plasma columns, extending to coronal heights - that we label as coronal swirling conduits (CoSCo).
