Have you ever wondered if a golf ball would sink or float in water? It’s a question that has puzzled many, and one that we’re going to answer today. We’ll look at the properties of a golf ball and how they interact with the properties of water to determine whether it will sink or float.

What are Golf Balls Made Of?

Golf balls are made up of several different components, including a rubber core, synthetic rubber coverings, and dimples on the surface. The core is typically made from balata or polybutadiene rubber which is designed to enhance feel when hitting off the tee. On top of this sits two layers of synthetic rubber coverings called mantles which help control spin around greens as well as providing durability when striking shots from fairway lies. Finally, most golf balls feature small indentations on their surface known as ‘dimples’ which helps reduce drag while in flight for increased distance off the tee.

Does A Golf Ball Float Or Sink?

The answer depends on several variables such as size and weight of the golf ball but generally speaking most standard sized (1.68-inch diameter) and weighted (46g) golf balls have an average density between 1.15-1.20 g/cm3 making them slightly less dense than water (1g/cm3). Therefore they should theoretically float! However because of air trapped inside each dimple there can be some variation in buoyancy so it really depends on factors like temperature and salinity changes too – meaning sometimes they may even sink!


So does a golf ball sink or float? Well depending on its size, weight, shape and environmental conditions it can vary – however generally speaking your average sized & weighted 46g ball should very slowly drift upwards due to its lower density compared to H20!
