ABSTRACT:
A toy dart includes a cylindrical wall having an inner surface, an outer surface, a first open end at one end of the cylindrical wall, and second open end at the other end of the cylindrical wall. At least two fins are attached to the outer surface of the cylindrical wall. In addition, a resilient, bulbous head portion is mounted on the cylindrical wall at the second open end thereof, the head portion defining a chamber adapted to contain fluid and having an opening formed therein so that the chamber communicates with an interior of the cylindrical wall. The toy dart is constructed and arranged for aerodynamic flight when thrown, and upon the bulbous head impacting a hard surface, the bulbous head portion deforms for moving fluid contained therein into the interior of the cylindrical wall. Other embodiments of the toy dart are further contemplated.
