Science Experiments / What sound would electric toothbrush vibrations cut into a vinyl record blank?

What we hear in any vinyl album is given by the shape of the grooves. I think nobody ever tried to decode these shapes with microscopes, because it would take too long. These grooves on the master are shaped by musical vibrations from the cutting stylus. But randomly we can try to cut them without music vibrations, tapping the stylus manually or with the help of an electric toothbrush (or any vibrator), while the vinyl blank is spinning. Would be interesting to hear what kind of music we get from these grooves.
