Usage of friction rod: gently tap the edge of the bowl with the friction rod, and then start friction before the vibration disappears. Hold the friction rod vertically at the edge of the bowl, stick it close to one side of the bowl, and slowly start friction along the upper edge until it makes a sound. This process should have both uniform and slow speed and uniform strength.
