An improved golf tee includes an outwardly flared portion to set and maintain a desired height of the ball above ground. The tee comprises a molded plastic member with a central longitudinal cylindrical shaft, an upper end and a lower end defining an overall length of 3.25+/0.25 inches. The upper end of the shaft transitioning into a conical golf ball support with an upper, circular rim, and the lower end of the shaft terminating in point with a rounded tip. A downwardly flared portion extends outwardly from the shaft between the upper and lower ends of the shaft, the flared portion terminating in a surface configured for ground contact when the pointed, lower end of the shaft in pushed into the ground. In the preferred embodiments, the distance between the conical ball support and the surface configured for ground contact is in the range of 1.5 to 2 inches.

A method to create a water permeable and water shuttling sand bunker by forming a continuous bunker edge, installing a drain assembly, installing a synthetic tufted surface and a continuous integral edge overlapping polymer mesh, depositing a non-woven dual smooth surfaced geo-textile over the mesh and forming a sand layer. Water flows from the continuous bunker edge over the synthetic tufted surface and the non-woven dual smooth surfaced geo-textile to the drain assembly preventing the drain assembly from clogging, thereby forming a water permeable and water shuttling sand bunker.

A tetherable golf tee and teeing system are disclosed herein. One golf tee includes a body including a first end for inserting into an external surface and a second end opposite the first end and a crown located on the second end, the crown configured for resting a golf ball thereon. The body further includes a hollow portion and a first aperture located between the first end and the second end to access the hollow portion and for tethering the golf tee to another object. The crown includes a second aperture to further access the hollow portion. A golf tee system includes at least two of the above golf tees tethered together via a tethering apparatus.

A golf swing mat system comprising a golf swing mat having a plurality of predefined openings formed therein. The plurality of predefined openings includes a plurality of guide element openings, a plurality of barrier element openings, and a plurality of ball support element openings. The golf swing mat system also includes a plurality of guide elements configured mounting in the plurality of guide element openings, a plurality of barrier elements configured for mounting in the plurality of barrier element openings, and one or more ball support elements configured for mounting in one of the plurality of ball support openings. The system also includes a hitting surface element coupled to the golf swing mat.

A reusable bottle cap includes a panel having a top surface and a bottom surface. A sidewall extends downwardly from a periphery of the panel away from the bottom surface. The sidewall is configured to engage with an outer surface of a bottle neck proximate a rim of the bottle when the reusable bottle cap is coupled to the bottle neck. A peg extends downwardly from the bottom surface of the panel and is spaced from the sidewall. The peg is configured to be spaced from an inner surface of the bottle neck when the reusable bottle cap is coupled to the bottle neck.
