ELI5 How to tasers put out 1,000,000+ volts when all they require to use is a couple AA batteries?

Always wondered about this.

They use a coil to raise the voltage while simultaneously limiting the current, so they don't electrocute the target.  The coil is powered by the batteries much like the spark plug in a car is powered by the 12 volt car battery, which is only huge because of the current needed to start the car, not to make the spark.
