1. A bottle containing transparent liquid and some amount of gas, for example, carbonated beverage, consisting of body and cover, a bottom part being made from transparent material and exceeding a diameter of bottom part of cover, which made also from transparent material, characterized in that the bottom of body and the bottom of cover are used as objective and ocular and preferably in vertical position of the bottle with liquid inside forms together a telescopic system, so a bottom of body and cover are at least partially limited and at least from one side (outside for example) are limited with axially symmetric optical refractor (spherical, for example), symmetric axes said refractors being coincided, forming optical axe of telescopic system, and a distance by optical axe between tops of nearest refractors of bottom of body -objective and front focal distance of bottom of cover-ocular. 2. A bottle according to claim 1, characterized in that the bottom parts of body and cover are made from materials, with refraction index equal to refraction index of liquid in the bottle, axially symmetric refractors limiting the bottom part of body and cover only from outsides. 3. A bottle according to claim 1, characterized in that only one component, as objective or ocular of telescopic system is made from material with refraction index equal to refraction index of liquid in the bottle, limited by axially symmetric refractors, and from other side as a lens and is limited by axially symmetric refractors from both (inside and outside) sides. 4. A bottle according to claim 1, characterized in that the bottom of the body is made as a lens and is limited by axially symmetric refractors from both (inside and outside) sides. 5. A bottle according to claim 4, characterized in that the body of the bottle is made form elastic material (polymeric, for example) and at least one part, containing a lens or attached with bottle detail, containing a bottle (orifice with cover for example) can possibly be after draining the bottle pressed inside of body of bottom part of body-objective with front focus of bottom part of cover ocular and creating a telescopic system without liquid between objective and ocular. 6. A bottle according to claim 1-5, characterized in that the cover is connected with the body by screw joint, the axe of which is coincided with optical axe of telescopic system, allowing to produce focusing of telescopic system by screwing and unscrewing the cover.
