    It might be interesting to measure the current on that. Do you think it will be over 10 Amps (the limit of most DMM)?

    Nowhere near 10A. The AA battery is not capable of that sort of current

    I checked some brand new freshly charged NiMH AAs (6 individual cells) with an ammeter at a dead short for just long enough to get a reading and they were able to generate ~4-6A, differed between cells.

    How should we go about measuring peak current in series with that gum wrapper?

    It has to capture the MAX amperage before the connection breaks open.

    You could use min/max on a multimeter or set a trigger on an oscilloscope. (Calculate 'I' after checking the resistance of the gum wrapper?)

    Sounds like a plan.
