balsa wood

Lightweight craft timber

Balsa wood is the lightweight timber of a tropical American tree, prized for its exceptional buoyancy and ease of cutting.

Model builders favor it for aircraft and architectural miniatures: We built the bridge out of balsa wood.

Despite its softness, balsa has a high strength-to-weight ratio, making it useful in surfboards, life rafts, and theatrical props.
