PRIORITY STATEMENT [0001] This application is a Divisional Application of and claims priority from U.S. application Ser. No. 10/629,212, which was filed Jul. 28, 2003, and which is currently pending, the contents of which is incorporated herein, in its entirety, by reference. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention consists of a seamless BB paintball having an oil-based fill material and an aqueous-based shell material and methods for manufacturing such seamless BB paintballs to provide safer and more environmental friendly materials. These BB pellets can be used for recreational games and military and police field training. [0004] 2. Description of Conventional Art [0005] Pellets currently used for recreational games and military and police training generally fall into the following two categories: BB pellets and paintballs. BB pellets 10 are manufactured to have a diameter of approximately 6 mm and typically exhibit a weight of approximately 0.12.about.0.33 grams. The BB pellet shown in FIG. 1 is comprised of non-environmental friendly solid plastic ball or a plastic-coated metal ball. Their advantages include low, cost, suitability for continuous firing, high accuracy, and widespread compatibility with plastic toy guns and simulation metal regulation pistols, rifles, or machine guns. When shot from a simulation metal gun, the pellets provide a sense of reality similar to the firing of real bullets. On the other hand, the pellets are manufactured by materials that are not decomposed readily, and therefore, they tend to pollute the. environment. In addition, when shot at a high speed, hard metal balls may potentially cause injury or death of the players. When used for recreational games and military or police field training, this type of pellet presents the disadvantages of reduced safety, biohazards and difficulty in accurate targeting. [0006] Conventional paintballs 20 have a diameter of approximately 17.5.about.17.7 mm and a weight in the range of approximately 3.8.about.3.9 grams. The paintball shown in FIG. 2 contains an edible solvent and dye, and is manufactured by environmental friendly materials. The paintball ruptures and releases the colored solution after striking the target, making a colored mark on the target that can be used to objectively assess the results of the game or training. Nevertheless, paintball have the disadvantages of being excessively large, excessively heavy, compatible only with special gains, and entirely incompatible with simulation guns. Since paintballs have an extremely soft outer shell, they cannot be loaded into the clip of the gun in a continuous fashion, and consequently cannot be fired continuously. While this is barely accepted in recreational games, it is practically useless as military and police training tools. [0007] U.S. Pat. No. 5,393,054 discloses one type of paintball that consists of a gelatin-coated distilled aqueous solution. The present invention not only differs from the aforementioned patent in terms of the percentages of gelatin and the enclosed material, but, also, employs an oil-based solution as the enclosed material. The present invention is thus substantially different from the aforementioned patent. [0008] With regard to a conventional 6 mm BB paintball 30 that are commercially available in Taiwan and in foreign markets, FIG. 3 shows the use of two hemispherical molds to manufacture two round, seamed, oval gelatin capsules filled with distilled aqueous solution containing a dye. Players who use this type of product perceive certain disadvantages, including the fact that the gelatin, capsule is too soft and cannot be fired continuously, and also that the capsule becomes even softer with time and soon cannot be used at all. In addition, the seams on the oval gelatin capsules render roughness in their surfaces, and thus affect firing accuracy. The present invention discloses a type of seamless BB paintball manufactured by a proprietary procedure that produces a paintball that represents a clear improvement over the conventional seamed products. [0009] The present invention employs new technology to manufacture seamless BB paintball 24 suitable for use in BB guns. This BB paintball is similar to BB pellet in size, but is manufactured by environmental friendly materials. The advantages of the present invention include environmental safety, continuous firing, high accuracy, and the ability to clearly mark the target. The present invention also provides a sense of reality similar to the firing of real bullets. BRIEF DESCRIPTION OF THE DRAWINGS [0010] The invention will become more apparent by consideration of the written description below in which example embodiments are detailed with reference to the attached drawings in which: [0011] FIG. 1 illustrates a conventional BB pellet; [0012] FIG. 2 illustrates a conventional seamed paintball; [0013] FIG. 3 illustrates a commercially available seamed BB paintball; [0014] FIG. 4 illustrates a seamless paintball according to an example embodiment of the invention; [0015] FIG. 5 illustrates molding equipment suitable for producing seamless paintballs according to an example embodiment of the invention; and [0016] FIG. 6 illustrates internal operation of an example embodiment of an apparatus for manufacturing seamless paintballs according to an example embodiment of the invention. [0017] These drawings are provided for illustrative purposes only and, unless specifically indicated, are not drawn to scale. The spatial relationships and relative sizing of the elements illustrated in the various embodiments, for example, the various components of the apparatus of FIG. 5 or the internal details of FIG. 6 with regard to the production of paintballs according to the invention, may have been simplified, reduced, expanded or rearranged to improve the clarity of the figure with respect to the corresponding description. DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS [0018] The seamless BB paintball 24 of the present invention employs a type of edible soft gelatin capsule as an outer shell. Enclosed in the shell is edible oil and dye, These materials are food grade, non-corrosive, biodegradable, and non-polluting. They are harmlessly excreted by the human digestive tract if accidentally swallowed. [0019] The seamless BB paintballs are manufactured by using an appropriate molding equipment based on the nature of mutual insolubility of distilled water and oil, the differential surface tension between the two solutions, and the property of gelatin that is melted at higher temperature and solidified at lower temperature. The molding equipment shown in FIG. 4 consists of three major parts: A control panel 40 located at the left side that provides power and controls of production conditions; a raw material storage tank 41 located in the center; and a molding apparatus 42 located on the right side. FIG. 5 shows two concentric nozzles, of which the inner nozzle sprays oil-based solution and the outer nozzle simultaneously sprays distilled aqueous solution. After the fluid of outer layer has completely coated the fluid of inner core instantly, and coated drops thereupon drips into the cooling oil; solidify and form ball-shaped gelatin capsules with smooth, seamless surfaces. As shown in FIG. 6, this is the finished seamless BB paintball 24 product of the present invention. [0020] The present invention employs food-grade soft gelatin capsules enclosing edible dye and oil. The oil can be either an edible synthetic oil or vegetable oil; it can be selected from peanut oil, soybean oil, corn oil, sunflower oil, olive oil, short-chain or medium-chain fatty acid. A "short-chain" fatty acid refers to a fatty acid with carbon chains consisting of eight fatty acids, while a "medium-chain" fatty acid refers to a fatty acid with carbon chain consisting of 16 fatty acids. Both short-chain and medium-chain fatty acid can be selected from saturated or unsaturated edible fatty acids. PEG (polyethylene glycol) or starch can be added when necessary to adjust the viscosity of the oil. PEG added can be a mixture selected from, two, or more than two types of PEGS. PEG of an average molecular weight between 200 and 6000 daltons is typically added. Edible starch, such as corn starch, potato starch, is also commonly added.
