The Tin Can Test
Spotted a shiny silver can standing guard by the recycling bin. Looked solid. Challenging! I stomped right over and clamped my claw tight around its belly. One heavy squeeze—CRUNCH! Gwahaha! Folded instantly into a crinkled metal puck! Not nearly tough enough for real armor, but what a glorious clatter! I kicked the squashed scrap into the corner pile for later. Good metal.
