Electricity works like this... Please note, I learned this in FIFTH GRADE... And some of the basics even before that from my parents... I also learned it in 8th, 9th and 11th grade.
Electricity is divided into two categories.
AC-Alternating Current, such as you would find in a outlet.
DC- Direct Current, such as you would find in a battery.
Alternating current is a current in which the direction of electrons is moving unpredictably. Ex: Forward, backward, up, down, etc, etc.
Direct Current is a current which is steady, continuous and goes in "one direction."

Basically how electricity works in the idiot kids' case is through a circuit. You know all about + and - on a battery? Basically touching two different wires completes the circuit, the heart is in between the arms and is directly hit. This causes arrhythmia and palpatations. Unable to effectively transfer blood throughout the body, the heart beats becomes ineffective, a person's body begins to shut down and they die. There you go... summed up in a paragraph.
