Abstract: A golf tee formed of a water-soluble substance, and manufactured by a method comprising preparing a water-soluble substance, molding the water-soluble substance and drying and hardening the molded object by heating. The golf tee, molded of the water-soluble substance, weathers when it is left on the ground.

Abstract: The golf tee comprising a clay substance which is efflorescent and a resin layer formed on the surface of the substance by applying a resin ultraviolet rays thereto. The resin layer increases the strength of the golf tee but becomes weak when placed in contact with water. The strength of the golf tee is very high, so that it can be easily inserted into a tee area of a golf course. Even though the golf tee is left in the ground, the resin layer is weakened when contacted with water and thereafter, the clay substance effloresces. Therefore, the golf tee does not pollute the environment of a golf course or adversely affect the operation of a lawn mower.
