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.

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.
Press the battery connector on to the battery terminals.
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.
