A bottle assembly includes: a pressurized bottle of fluid having an elongated body and a neck extending contiguously from the body to a top portion including an outwardly projecting annular flange; and a bottle severing mechanism including a bottle striker carried by the bottle and residing below the top portion. The bottle striker includes: a frame mounted to move relative to the bottle in response to an impact by a saber while remaining coupled to the bottle; and a striking edge extending from the frame and aligned with a lower surface of the annular flange of the bottle, such that movement of the frame relative to the bottle causes the striking edge to strike the lower surface of the annular flange to sever the top portion of the bottle from the body.
