Abstract

A lawn dart having front and rear portions, the front portion comprising a cylindrically shaped, hollow member fabricated from a flexible material, such as plastic. An elongated flexible tip in first, second and third embodiments is formed as a part of the hollow member, and in a fourth embodiment, is a second component coupled to the hollow member, the flexible tip absorbing and dissipating the energy of impact. A material to provide weight stability to the dart is positioned in the hollow portion of the cylindrical member. In the preferred embodiments, air cushions within the hollow portion act with the flexible tip to enhance the absorption and dissipation of the impact energy. The rear portion of the dart is in the preferred embodiments, permanently secured to the front portion. A target member, comprising a closed ended member, having netting attached thereto, is anchored to the ground and supported thereabove by a plurality of anchor members. The dart is aimed at the target, and if aimed correctly, the dart will be caught within the netting in an upright position.
