Part 3/7:
He shows the different textures of his homemade rosin: a hard, crystalline form, a softer, more gooey type, and an intermediate consistency. For the experiment, he uses the softer rosin, applying it to the aluminum rod to facilitate the vibrational transfer.
The Importance of Balance and Positioning
Paul emphasizes the necessity of finding the rod's center point for the experiment to succeed. Proper balancing ensures the resonance effect is accurate and consistent. By positioning the rosin at specific points—likely the center—he sets the stage for vibration to propagate effectively along the rod.
