Experience first-hand the science of electricity and circuits with the Magic Ghost Ball.
This cool ball demonstrates the principles of energy transfer and of open and closed circuits, while being loads of fun. Simply cover the foil discs with your fingers to close the circuit and light up the ball, which will also make ghostly sounds! Remove one or both fingers to open the circuit, and therefore turn off the lights and sounds.
An ingenious and inexpensive device to teach and learn about electricity, circuits, conductors and electrons. Or just for fun.
What You Get
Magic Sensor Ghost Ball. Pack includes one sensor ball that lights up and makes sound when you complete the circuit with your hands. Long-life batteries are included and not replaceable.
How does it work?
The challenge: how do you get electricity to flow through the circuit and the ball to pulsate with sound and light? There is no switch, just two metal electrodes.
The Magic Ghost Ball is an example of an open circuit. Upon investigation it will become obvious that when you touch the metal electrodes the electricity flows and the ball comes to life. By touching the electrodes you have closed the circuit, no more gaps means electrons can flow.
Group demonstrations are always a hit: have everyone hold hands in a circle, then include the Magic Ghost Ball by having two people touch one electrode each. The electricity flows through everyone in the circle to light up the ball.
What happens when someone lets go of the person next to them? A gap is created just like a switch. This demonstrates that people are good conductors of electricity, but what about other materials? Use the energy ball to find out.
