The bar soap that floats is Ivory.
Why Does Ivory Soap Float?
-
Intentional Air Incorporation: Unlike most bar soaps, Ivory soap is made with a small amount of air whipped into it during the manufacturing process. This technique decreases the soap's density, making it less dense than water.
-
Buoyancy: Because Ivory soap is less dense than water, it floats, following the principle of buoyancy. Objects float in water when their density is less than the density of water.
The History of Ivory's Floating Property
The floating nature of Ivory soap has been a key characteristic throughout its history, often associated with the concept of purity and cleanliness. This attribute, whether accidental or planned, has played a significant role in the brand's identity.
Benefits of Floating Soap
While the primary benefit of floating soap is often marketing appeal, it also has practical uses.
- Makes the soap easier to locate in the bathtub or shower.
Summary
In conclusion, **Ivory** bar soap floats due to a deliberate process of incorporating air during manufacturing, which reduces its density below that of water.
