Demonstrate electrical continuity using the ‘Energy ball’ (also known as a Cosmic Ball). Simply touch the ball’s metal strips to complete a circuit and the ball lights.
To demonstrates electrical conductivity through different materials, and even demonstrates electrical conductivity through the human body by touching the two contacts. For a group activity, get students to form a circle by joining hands, using an Energy Ball to complete the circuit to make the ball light.

What makes the energy ball work?
Inside the energy ball is a simple circuit that is completely self-contained. By touching both sensors, the circuit is completed by electrons flowing through your body or another conductive material such as a paper clip. Materials that activate the energy ball
are good conductors, meaning they pass electrons easily. Materials that do not activate the energy ball are poor conductors (or insulators), meaning they do not pass electrons easily. Your students will enjoy finding different ways to activate the ball
