Not so long ago, there would have been only one answer to this question. Today, however, the question begs clarification with a follow-up question: What are the breasts made of? Natural breasts and fake or enhanced breasts have very different physical properties.
Natural breasts are composed of 90% body fat. The glands that produce milk and the ducts through which the milk flows are actually very small parts of the total breast. Whether something floats or not depends on the density of the object and the type of water. Salt water is denser than fresh water. If an object has less density than the water, it rises to the top, or floats. Human body fat is less dense than water. In unscientific experiments done by Spike TV, natural breasts are shown to float. Whether or not the breasts can support the entire upper body, making a whole person float, depends on the size of the breasts. If the breasts were detached from the body, any size would float in both fresh and salt water.
If the breasts are not real, the answer to another question must first be ascertained: What, exactly, are the breasts made of? Almost all fake breasts are made of plastic bags filled with either a saline solution or silicone. Silicone is denser than both fresh and salt water. This means that silicone breasts will sink. Saline solution is another name for salt water. Since salt water is denser than fresh water, saline breasts will sink in fresh water. In most salt water, saline breasts will just hang in place at the depth they are placed. They won’t sink and they won’t float. The saline breasts may sink or float very slowly, though, depending on the exact salinity of the water.
