    Guys, will a 12V car battery "blow up" if it is shorted out with a nichrome wire, to make a Macgyver heating element to boil water?

    To a 12V car battery, what might appear as a short to a smaller battery might be just a small load.

    What is the resistance of the wire, and why do you ask?

    To make a Macgyver-ish water boiler. Say, when the power is out, during a storm.

    you are not going to be able to immerse a nichrome ( or any other) wire directly into water, else it will just short out. It will need to be insulated in ceramic or something else that will conduct heat but not electricity
