How was this done?

Not knowing the particulars, one of the tags is photography which leads me to believe it is still photography time lapsed.
With the amount of blur in the movement, the shutter speed would be less than 1/30th of a second. Shooting about a frame per second. Now translating that to a motion camera would be camera dependent. With film, you would need an intervalometer to match such a slow shutter speed.
180º shutter angle @ 24fps is the equivalent to 1/48th shutter speed (1/50th) on a SLR still camera, which will give a blur on most moving subjects. You can get the fps down to around 1fps or 2fps on most cameras, but your still restricted to the 180º shutter angle which dictates the 1/48th exposure time. That is due to the reflex mirror for the viewing optics. The intervalometer will keep the mirror open for the set time and also block the light from passing into the lens when the mirror is closed so that light doesn't leak around the mirror into the gate. This will allow for extended exposure time to the film.
Whole different story with digital cameras... but the math is the same.
