Movie and photograph of super gigantic Tesla coil which runs violet lightning of purple

An oversized Tesla coil is a movie and a photograph which are blowing out lightning violently. The Tesla coil is also big, so the lightning is also getting thick. If you are doing such experiments in the neighborhood, it seems to be mistaken for lightning.

Details are as follows.

The spark from this Tesla coil was also 3 meters high. It seems that Tesla Coils are sometimes coming out sometimes at entertainment etc. overseas, but I do not see much in Japan.
