What wood is the most boyant?

The most buoyant wood is generally considered to be balsa wood. Balsa is lightweight and has a low density, which allows it to float easily on water. Its high strength-to-weight ratio makes it popular not only in model building but also in various applications where buoyancy is essential. Other woods, like cedar and certain species of pine, can also be buoyant, but balsa is typically recognized as the lightest and most buoyant overall.
