Description
 
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 up and buzzes. This simple product safely demonstrates electrical conductivity of different materials, and even demonstrates electrical conductivity through the 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 up and buzz.
