The shell comprises a mixture of gelatin and mineral oil; the inner filler composition comprises a mixture of starch, oil, an emulsifying agent and a spreading and surfacting agent. The shell further comprises a non-crystallizing polyhydric alcohol, glycerine, and water. The inner filler composition may further comprise a pigment. The non-crystallizing polyhydric alcohol may be sorbitol, the oil is Soya oil and the emulsifying agent is emulsifying wax. The spreading and surfacting agent may be Tween® 20 and the pigment may be TiO2. ## Claims ### Claim 1 A paintball comprising: a shell containing an inner filler composition; wherein said shell comprises a mixture of a gelatine and a mineral oil; and wherein said inner filler composition comprises a mixture of a starch an oil an emulsifying agent and a spreading and surfacting agent wherein said mineral oil of said shell interacts with the gelatine to create a barrier preventing penetration into said shell of said oil contained in said inner filler composition and wherein said mineral oil further balances out interaction with said oil of said filler composition; wherein said starch is used as a thickening and binding agent and provided to completely replace a polyethylene glycol; wherein said emulsifying agent acts as a binding and stabilizing agent between said starch and said oil of said filler composition and is provided to keep heavier particles of said filler composition in suspension and to improve washability; wherein said spreading and surfacting agent acts as an additional binding agent between said starch and said oil of said filler composition and provided to improve washability; and wherein the proportions between said starch and said oil in said filler composition are precisely balanced and formulated to achieve maximum performance, thickness and stability of said filler composition in extreme cold weather conditions, ranging from 30% starch and 65% oil at the lower level to 50% starch and 45% oil in the upper level, and wherein said emulsifying agent and said spreading and surfacting agent contain the remaining 5% of the total mixture; ### Claim 2 (depends on 1) Paintball according to claim 1, wherein said shell further comprises a non-crystallizing polyhydric alcohol, glycerine, water and a pigment. ### Claim 3 (depends on 2) Paintball according to claim 2, wherein said non-crystallizing polyhydric alcohol is non-crystallizing sorbitol solution. ### Claim 4 (depends on 1) Paintball according to claim 1, wherein said oil is Soya oil, said emulsifying agent is emulsifying wax and said spreading and surfacting agent is Polysorbate 20. ### Claim 5 (depends on 2) Paintball according to claim 2, wherein said pigment is TiO2. ### Claim 6 (depends on 2) Paintball according to claim 2, wherein said shell contains 39.29% gelatine, 4.34% non-crystallizing polyhydric alcohol, 6.89% glycerine, 8.16% mineral oil and 41.33% water. ### Claim 7 A paintball comprising: a shell containing an inner filler composition; wherein said shell comprises a mixture of a gel-forming agent and a barrier agent; and wherein said inner filler composition comprises a mixture of a starch a carrier agent an emulsifying agent and a spreading and surfacting agent; wherein said barrier agent of said shell interacts with said gel-forming agent of said shell to create a barrier preventing penetration of the carrier agent of said filler composition into said shell and wherein said barrier agent is provided to balance out interaction with said carrier agent of said filler composition; wherein said starch is used as a thickening and binding agent and is provided to completely replace a polyethylene glycol; wherein the proportion of said starch and said carrier agent in said filler composition is precisely balanced and formulated to achieve maximum thickness, performance and stability to withstand extreme cold weather conditions; wherein said emulsifying agent facilitates binding between said starch and said carrier agent and provided to keep heavier particles of said filler composition in suspension thus improving stability of said filler composition; and wherein said spreading and surfacting agent further acts as an additional binding agent between said starch and said carrier agents. ### Claim 8 (depends on 7) Paintball according to claim 7, wherein the proportion of said starch and the carrier agent in said inner filler composition is from 30% starch and 65% carrier agent at the lower level to 50% starch and 45% carrier agent in the upper level, and wherein said emulsifying agent and said spreading and surfacting agent contain the remaining 5% of the total mixture. ### Claim 9 (depends on 7) Paintball according to claim 7, wherein said shell further comprises a humectant rubberizing agent, a diluting agent, glycerine and a pigment. ### Claim 10 (depends on 9) Paintball according to claim 9, wherein said humectant rubberizing agent is a non-crystallizing polyhydric alcohol. ### Claim 11 (depends on 9) Paintball according to claim 9, wherein said gel-forming agent is gelatine, said diluting agent is water, said carrier agent is oil, said emulsifying agent is emulsifying wax and said spreading and surfacting agent is Polysorbate 20. ### Claim 12 (depends on 10) Paintball according to claim 10, wherein said non-crystallizing polyhydric alcohol is non-crystallizing sorbitol solution. ### Claim 13 (depends on 11) Paintball according to claim 11, wherein said oil is Soya oil. ### Claim 14 (depends on 9) Paintball according to claim 9, wherein said pigment agent is TiO2. ### Claim 15 (depends on 11) Paintball according to claim 11, wherein said shell contains 39.29% gelatine, 4.34% non-crystallizing polyhydric alcohol, 6.89% glycerine, 8.16% oil and 41.33% water.
