I think maybe the spray from the needlepoints is charging the ends of the pingpong balls (or in mine the piece of maskingtape) and this is attracted to stuff around the thing because the charged part of the balls makes a stronger e field.
I fixed charge can not cause the 360 degree sustained rotation. The rotor should cog and eventually stop at the point of greatest attraction if the cause of motion is the charge on the ping pong ball.
