    the water and the container would need to be very clean and the container would need to be very smooth and free of surface defects for that to happen. even microscopic cracks or scratches in glazing or glass can act as a highly effective starting point for boiling.
    think scraping over the bottom of a glass with a spoon: that might be enough already to create those kinds of scratches.







  • LiPo batteries will not last 10 years, even if unused.

    They will self-discharge in a matter of a few years (the exact time this takes depends a lot on the quality of the cell btw.). After you reach a critical level of discharge the electrodes inside the battery will start to become irreversibly damaged (typically below 2.7V but this can vary a little depending on exact type).
    after this damage becomes severe enough the cell can be considered dangerous because trying to recharge it at this point could result in an explosion. the same is true if a LiPo cell is damaged by some other method, like crushing or extreme temperatures.
    if you do not recharge a cell that was damaged from a ultra deep discharge you are relatively safe though. the most probable danger from such a cell would then be leaking electrolyte because the hermetic seal could be damaged from long-term corrosion / environmental damage.
