have been observed in some particular events independently of the scale. Recent high-resolution observations have shown that the base of some chromospheric jets [@LiuW11; @ZhinchengZ16] have the same morphology and presence of bi-directional flows seen in examples of larger-scale coronal jets [@Shibata92]. This suggests that they may share a common underlying topological structure: a 3D null point and its fan/spine separatrices [@MorenoInsertis08; @LiuC11; @ZhangQM12; @ZhinchengZ16]. Regarding the morphology of the spire, using Hinode data, @Suematsu08 and latter @Sterling10a have noted that spicules present a double-stranded morphology that is similar to the emission pattern observed in coronal jets. Supersonic, though possibly sub-Alfvénic velocities have also been noted for chromospheric events [@Tian14] as well as jets developing in the corona [@Cirtain07]. Jet-like events also tend to recur homologously at the same location independently of their size; this property has been commonly observed for spicules [@DePontieu07], chromospheric jets [@Tian14], and coronal jets [@JiangY07; @Chifor08a; @Chifor08b].

One of the most puzzling properties that all these events display is the common presence of helical structure and/or twisting motion. Signatures of rotating structure are present in a noticeable sample of all these phenomena in spite of their very different environments. On the larger end of the
