Pressure Valve Inspection

I marched up to a massive aluminum soda can towering over the desk mat like a pressurized hull tank. Cold beads of condensation were dripping down the brushed metal, so I gripped my trusty salvaged paperclip and shimmied up onto the rim. The pull-tab looked just like a heavy release hatch valve. I hooked the curved end of the clip right under the ring and gave it a solid test tug with both claws. The metal tab groaned slightly, but that seal is built tough for deep-sea depths. I didn't breach the hatch yet, but now I know the latch mechanism.
