Science Buddies: "Ask an Expert"

Could someone tell me how to demonstrate How electrical current runs through the body. This is foor my Science project at school---Thanks

Since our human body is composed of at least 70% of water, perhaps you can demostrate how water conducts electricity hence the human body also conducts electricity.

Here are some examples that show how different objects act as electrical conductors:

Perhaps you can borrow these methods to demostrate how water conducts electricity.
