The present invention teaches an arrowhead of foam, having a front aperture leading to a front cavity: the front cavity is either an injectable paint cavity or a partial spherical shape, the aperture formed by the bisection of the cavity with the front end of the arrowhead and smaller in diameter than the cavity. The cavity diameter may be such that the resilience of the foam secures a paintball therein. The rear end of the arrowhead has a second aperture dimensioned and configured to secure an arrow shaft therein on a threaded connector. The arrowhead has a shock absorber mechanism and other details which provide for extreme cushioning of impact.

1. An arrow for use with a standard diameter paintball, the arrow comprising: a shaft, the shaft having a threaded internal bore having an internal diameter, and front and rear ends;fletching on the shaft at the rear end of the shaft;a nock at the rear end of the shaft;an arrowhead having a body having a length and front and rear ends, the arrowhead made of resilient foam,the arrowhead having on the front end a first aperture leading to a first cavity,the first cavity being partially spherical in shape, the spherical shape being bisected by the front end of the arrowhead to create the first aperture, the center of the spherical first cavity being disposed within the arrowhead, whereby the portion of the sphere made by the first cavity is more than one half of a complete sphere;the first cavity having a diameter sufficient to secure such standard diameter paintball by means of the resilience of the foam when such standard diameter paintball is inserted therein through the first aperture;the first aperture having a diameter smaller than the diameter of the first cavity but large enough to allow insertion of such standard diameter paintball due to the resilience of the foam;an connecter dimensioned and configured to mechanically engage the bore of the arrow shaft;a shock absorber, the connecter engaging the shock absorber, and the shock absorber engaging the arrowhead;the arrowhead mounted to the arrow shaft by the connector;on the rear end a second aperture leading to a second cavity, the rear aperture having dimensioned and configured to accept such arrow shaft;the shock absorber disposed within the second cavity;a shock absorber body having a generally cylindrical configuration with an internal bore running from a front end to a rear end of the shock absorber body, the internal bore having a first portion having a first bore diameter and a second portion having a second bore diameter, the first portion at the front end and the second portion at the rear end of the shock absorber body;a cap, the cap secured to the front end of the shock absorber body, the cap covering the internal bore at the front end;the connector having a head having a head diameter and having a connector portion having a diameter, the head diameter larger than the connector portion diameter;the first bore diameter being larger than the head diameter, the second bore diameter being smaller than the head diameter but larger than the connector portion diameter;the connector disposed with the connector portion in the second portion of the bore, and the head in the first portion of the bore;whereby the connector head may be trapped within the first portion of the bore by the cap covering the internal bore at the front end and the smaller second bore diameter at the rear end of the internal bore;a coil spring disposed within the bore between the head and the cap, the coil spring urging the connector toward the rear end of the arrowhead;a rubber bumper disposed within the coil spring. 2. The arrow of claim 1, wherein the arrowhead further comprises: a front section and a back section, the first cavity being in the front section and the second cavity in the back section. 3. The arrow of claim 2, further comprising: an intermediate section of the arrowhead between the front section and the back section. 4. The arrow of claim 3, further comprising: a third cavity, the third cavity disposed within the first section of the arrowhead, the third cavity having at least one air vent which acts to vent the third cavity slowly when the arrowhead is compressed by an impact. 5. The arrow of claim 3, wherein the resilient foam comprises: ethylene-vinyl acetate foam. 6. The arrow of claim 1, for use with a whistle, the arrow further comprising: an opening on a side portion of the arrowhead, the opening dimensioned and configured to accept such whistle therein. 7. An arrowhead for use with paint, the arrowhead comprising: a body having a length and front and rear ends, the arrowhead made of resilient foam,the arrowhead having on the front end a first aperture leading to a first cavity,a connecter;a shock absorber, the connecter engaging the shock absorber, and the shock absorber engaging the arrowhead;on the rear end a second aperture leading to a second cavity, the shock absorber disposed within the second cavity;a shock absorber body having a generally cylindrical configuration with an internal bore running from a front end to a rear end of the shock absorber body, the internal bore having a first portion having a first bore diameter and a second portion having a second bore diameter, the first portion at the front end and the second portion at the rear end of the shock absorber body;a cap, the cap secured to the front end of the shock absorber body, the cap covering the internal bore at the front end;the connector disposed with the connection portion in the second portion of the bore, and the head in the first portion of the bore; whereby the connector head may be trapped within the first portion of the bore by the cap covering the internal bore at the front end and the smaller bore diameter at the rear end of the internal bore; a coil spring disposed within the bore between the head and the cap, the coil spring urging the connector toward the rear end of the arrowhead;a rubber/foam bumper disposed within the coil spring. 8. The arrowhead of claim 7, further comprising: a front section and a back section, the first cavity being in the front section and the second cavity in the back section. 9. The arrowhead of claim 8, further comprising: an intermediate section of the arrowhead between the front section and the back section. 10. The arrowhead of claim 9, further comprising: a third cavity, the third cavity disposed within the first section of the arrowhead, the third cavity having at least one air vent which acts to vent the third cavity slowly when the arrowhead is compressed by an impact. 11. The arrowhead of claim 7, wherein the first cavity partially spherical in shape, the spherical shape being bisected by the front end of the arrowhead to create the first aperture, the center of the spherical first cavity being disposed within the arrowhead, whereby the portion of the sphere made by the first cavity is more than one half of a complete sphere; the first cavity having a diameter sufficient to secure such standard diameter paintball by means of the resilience of the foam when such standard diameter paintball is inserted therein through the first aperture;the first aperture having a diameter smaller than the diameter of the first cavity but large enough to allow insertion of such standard diameter paintball due to the resilience of the foam.
