The September 1995 SCIENCE SCOPE magazine described a demonstration experiment in which one regular-sized bar of Ivory Soap was placed in a microwave oven for two minutes. The soap forms a rigid, irregular, "cumulus" extrusion approximately 3X in size. Ivory provides a more dramatic effect compared to other brands. Proctor and Gamble advertises Ivory Soap to be 99-44/100% pure. It contains vegetable oils, animal fats, fragrance and, of course, the whipped air that provides its famous buoyancy ("The soap that floats!").
