Bottle striking

A method of opening a pressurized bottle of fluid, the method comprising:

• holding a bottle assembly in a substantially fixed position, the bottle assembly comprising:
• a pressurized bottle of fluid having an elongated body and a neck extending contiguously from the body to a top portion comprising an outwardly projecting annular flange, an opening, and a closure received by the opening;
• a bottle severing mechanism comprising:
• a collar mounted on an outer surface of the neck of the bottle;
• a bottle striker supported on the bottle by the collar and configured to move relative to the bottle, the bottle striker residing below the top portion, the bottle striker comprising a striking edge aligned with a lower surface of the annular flange of the bottle;
• and
• a link comprising a first end connected to the collar and a second end coupled to the top portion of the bottle;
• and
• a retention member comprising a mesh at least partially defining an enclosed area surrounding the top portion of the bottle, the mesh configured to permit a discharge of liquid from the enclosed area while retaining solid particles within the enclosed area;
• and
• impacting a portion of the bottle assembly with a saber with sufficient force to move the striking edge relative to the bottle and cause the striking edge to strike the lower surface of the annular flange to sever the top portion of the bottle from the body.
