Abstract:

The lazer ball is a foamed ball or projectile which glows under particular lighting conditions and which can be fired through a standard air gun, such as a paint ball gun. The lazer ball can be prepared from any suitable foam material which is capable of being molded or extruded into a spherical shape, is compressible when pressure is applied to it and can return to its original shape when pressure is released. Other properties of the lazer ball include a density of between about 11. 0 to about 15. 0 pcf, a skin thickness of between about 0. 015 and about 0. 025" and a shore "A" durometer of between about 35. 0 and 45. A preferred foam material is an integral skin urethane foam system. Standard foam systems may require chemical modification in order to meet the required surface properties.
