Colored paraffin behaves differently — even when it’s the same material. The pink layer sounds softer, while the orange one gives a drier, sharper crunch. Color affects the density of the coating, and that changes the sound. One single layer on chocolate breaks fast with a short “click.” Multiple layers — up to 10 — crack slowly, step by step, creating a deeper and richer sound. The more layers, the longer and more satisfying the crunch. Paraffin shows it clearly: color, thickness, and number of
