THE  BLACK THINGS WHICH   LOOK  LIKE  WHEELS  ARENT WHEELS  THEY  ARE  IMMOVABLE  AND NON  ROTATARY.  AND  ARE  USED  JUST TO  GRIP  VDG    ON  THE  FLOOR.

taping a ground wire to a concrete floor will not provide ground. concrete does not conduct.

You'd be surprised how conductive it actually is, in practice.

What happens or not?

No connect to a water pipe assuming the are copper.

Your black pulleys may be conductive as the black is often carbon black.

Your pulley is likely to be quite conductive, because "black" is often carbon powder.

Black plastic is often conductive - test it with a multimeter.

Explain how you think it should be working. I can't tell what the parts are supposed to be doing so I can't tell you what is wrong with it.

Your apparatus doesn't resemble this pictorial diagram very closely.   Your negative comb should not be grounded.  It should be used to draw sparks from your dome (can?).
