How do I Make a 9 Volt Spark?
A standard 9-volt battery may be used for this project. (battery image by Edsweb from

A 9-volt alkaline battery is capable of providing several hours of electrical power to a small electronic device. Under the right conditions, a fully charged 9-volt battery can also supply enough electrical energy to create a small electrical arc.

One way to create an electrical arc, or spark, is to create a short-circuit condition between the two terminals on the battery.

  1. 1

    Strip 1/8 of an inch of insulation from the free ends of the battery connector wire leads. Make sure that the exposed wire ends do not touch each other.

  2. 2

    Press the battery connector on to the battery terminals.

  3. 3

    With a flicking motion, touch the tips of the exposed wire ends together. A small electrical spark will result between the wire tips.

Tips and warnings

  • Do not allow the wire ends to touch each other for more than a few seconds. The battery will overheat and possibly explode if the short-circuit is maintained for more than a few seconds.
