Fun Facts About Wood

Hardwoods and softwoods are distinguished by their structure, not by their strength, so some softwoods are actually harder than some hardwoods. Deciduous trees (trees that lose their leaves in the fall) are hardwoods and coniferous trees (trees that keep their needles year-round) are softwoods. Yew, a softwood, is harder than balsa, a hardwood.

Some ironwoods are so dense that they sink in water.

Ping-pong balls are made with celluloid, which is a byproduct of the paper-making process. Celluloid is used in ping-pong balls because it is easily molded and shaped, while allowing for the high-bounce property of the balls.

Your snack may contain wood components! Packaged cookies and cupcakes, shredded cheese, bread, cereal, sour cream, sauces, and thousands of other foods are made with cellulose, hemicellulose, and lignin. Hemicellulose is used as a food additive to improve physical qualities such as smoothness, creaminess, and mouth feel in products including dressings and sauces. Cellulose is used to sweeten, stabilize, and add fiber to many food products. Lignin can make muffins fluffy.

Wood’s hardness is measured on the Janka scale, which tells you how much force is required to embed a 0.444” ball of steel halfway into the wood. Ironwood, one of the hardest woods in the world, has a Janka rating of 5,060 lbf (pounds-force), while balsa, one of the softest, has a rating of just 67 lbf.

Clothing made of rayon and acetate is made from the cellulose fibers in wood pulp.
