Abstract:
1. A marker tag dart for use in a marker tag dart gun comprising: a foam marker tag dart body; an elastic cap attached to a one end of the foam marker tag dart body; the elastic cap defining, at least in part, a chamber therein; the elastic cap having a substantially self sealing area for temporary penetration for injection of a liquid into the chamber; the elastic cap also having a plurality of irregularities in a forward end of the cap opposite the foam marker tag dart body, the irregularities configured to retain liquid in the chamber when the elastic cap is not elastically deformed, and to release liquid in the chamber when the forward end of the cap impacts an object; the elastic cap again being able to retain liquid in the chamber when the elastic cap is again not elastically deformed; whereby after one impact, the marker tag dart may be ready for reuse by replacing the liquid released during the prior impact.
