[0036]It is an object of the present invention to replace current paintball formulations and soft-gelatin production methods by providing a new paintball, which is capable of encompassing a wide range of features and benefits, which those of ordinary skill in the art would appreciate as not being achievable with current formulations or production methods. These features include the capacity to manufacture paintballs and projectiles with greater precision, speed, and having similar or better quality than today's existing standards. Moreover the paintball of the present invention utilizes renewable, substitutable, non-animal derived shell materials and eliminates the need to employ hydrocarbon based fill materials, which are in short supply and are expensive.
[0037]Still another object of the present invention is to manufacture a paintball that is substantially cheaper to produce than the current gelatin processes, but which also yields new combinations and embodiments that are not currently achievable by today's practices. These include but are not limited to, encapsulating multiple fill materials that maintain their respective spatial orientation within a paintball during production without the aid of internal barriers and/or separate chambers. These fill materials may consist of or demonstrate, multiple colors having daytime and/or nighttime marking capabilities that provide a highly visible mark upon a target. Further, upon marking a target the fill of the preferred embodiment quickly becomes a gel and maintains it's form and does not "run" off of the target. These fill materials are also environmentally "friendly" and highly suitable for outdoor use where paintball is predominately played.
