Hey guys. Electricity is a fascinating thing that I steer clear of, however, when scrolling YouTube a decade ago, I found out that there are hand-cranked machines that make sparks. Do any of you guys own one of these electrostatic machines? If so, what got you into owning one?

Here is the video: [link deleted by moderators] His basic idea is to take the spacetime interval and add a 5th term for the 5th dimension he is describing so it looks like: $$\Delta S^2 = c^2\Delta t^2 + c^2\Delta w^2 - \Delta x^2 - \Delta y^2 - \Delta z^2 $$ where w is the difference in time...
