Hidden TreasureMy landlord had some builders in to remove a staircase in an outbuilding when a rusty biscuit tin fell out from under the woodwork.
What wonders were in this hidden treasure box? Two live hand grenades and 40 rounds of ammunition. From WW2. I've never seen builders run before.
What hidden treasures have you uncovered?

I've rediscovered my pedantryThanks to xlux. Aluminium does rust. As you state yourself - "the skin forms a thin layer of oxidation", by which I take you to mean "the Aluminium in contact with the air oxidises to form a protective layer of Aluminium Oxide which shields the remaining Aluminium". That oxidation is "rust". Aluminium also "rusts" extremely quickly - you can see it: Scratch a can and watch as the shiny metallic Aluminium turns to dull grey Aluminium Oxide. So, realistically, you never see Aluminium that hasn't "rusted" for longer than a few seconds, outside of an oxygen-free environment.
*Realises Chemistry GSCE was worth it after all.
