Electrostatic demonstrations: field lines between two charged spheres not the same polarity

Electrostatic demonstrations: electrical field lines between two charged spheres not the same polarity.
The electrical field lines between two not equally charged spheres are visible through semolina grains in castor oil, which are in a massive plexiglass box.
After the experiment, the liquid can be stirred with the small white bar magnet, so that the semolina grains are almost in a random distribution again.
Best wishes

this one surprised me,
could you do this one again but with the spheres much closer (or larger) ?
now if you could put electric field sensitive dye to show field gradients another layer of understanding/apprecation could be revealed.
there are such dyes but I have no experience with them.
