"What is electricity?" - Julian, 8, Memphis, TN

The answer is no one invented electricity, and it's just always there. "Electricity is the flow of electrons. Electrons are one of the basic building blocks of the universe," Hines explains. "Everything is made of three basic particles, neutrons, protons and electrons. Whenever those electrons start moving, that's electricity."

Humans have always known that electricity is there, because we've known about lightning and static electricity. But we've figured out how to get electricity to move in the right direction using generators, we can generate all the electricity we need to power our world.
