Why does wood float?
Wood is an extraordinary material with numerous unique features, among which the ability to float on water. But why does wood float? This article explores the scientific reasons behind this fascinating characteristic and how some exceptions prove the rule.
Wood density and floating?
The ability of wood to float is mainly due to its density, which is generally lower than that of water. Density refers to the mass of a material per unit volume.
When the density is inferior than that of water (about 1 gram per cubic centimeter), the material floats. Wood, with an average density ranging from 0.3 to 0.9 grams per cubic centimeter depending on the species, naturally tends to float.
The cellular structure of wood
Another crucial factor that contributes to the floating of wood is its cellular structure. Wood is made up of cells that form a network of fibers and empty spaces. These spaces are often filled with air, which makes the wood lighter and less dense than water. This porous structure acts like an “air chamber”, allowing the wood to float easily on the water’s surface.
Rule exceptions: woods that sink
Although most type of woods float, some exceptions do exist. Certain wood, such as ebony, have a very high density that can exceed that of water. Ebony, for example, is known for its high density and hardness, that can exceed 1 gram per cubic centimeter. This means that ebony, unlike other woods, can sink when put into water.
Fabema and wood knowledge
In Fabema we dedicate ourselves to providing furniture solutions that combine aesthetics, functionality and sustainability. We use carefully selected woods, treated to preserve their best natural qualities.
Our experience allows us to create furniture and structures that not only meet the highest quality standards, but also enhance the unique features of wood, such as its ability to float. each Fabema project is a testament to our commitment to craftsmanship excellence and environmental sustainability.
