Fun Facts

The Touch-N-Glow may look like a simple ping-pong ball with two pieces of metal, but when both pieces of metal are touched

simultaneously, the ball lights up and makes noise. Have fun while exploring the science of the unique Touch-N-Glow Ball!

•• Light bulbs work in much the same Light bulbs work in much the same Light bulbs work in much the same way as an Touch-N-Glow. The filament . The filament . The filament in a light bulb (the small wire that emits in a light bulb (the small wire that emits in a light bulb (the small wire that emits light in the middle of the bulb) provides light in the middle of the bulb) provides light in the middle of the bulb) provides the connection to close the circuit. A dead the connection to close the circuit. A dead the connection to close the circuit. A dead light bulb stops emitting light because the light bulb stops emitting light because the light bulb stops emitting light because the filament breaks and the electricity cannot filament breaks and the electricity cannot filament breaks and the electricity cannot travel through it.• Insulators like certain kinds of rubber Insulators like certain kinds of rubber are used to cover electrical cords are used to cover electrical cords are used to cover electrical cords so that they are safe to touch. Be so that they are safe to touch. Be so that they are safe to touch. Be careful not to touch an electric cord careful not to touch an electric cord careful not to touch an electric cord that does not have an insulator.

A circuit is a “circle.” This is not a coincidence. A circuit is a “circle.” This is not a coincidence. A circuit is a closed circle through which electricity flows. If closed circle through which electricity flows. If closed circle through which electricity flows. If there is a break in the circle or circuit, the electricity there is a break in the circle or circuit, the electricity there is a break in the circle or circuit, the electricity cannot flow through it. When you flip a light switch cannot flow through it. When you flip a light switch cannot flow through it. When you flip a light switch to the “on” position, the electrical circuit is closed, to the “on” position, the electrical circuit is closed, to the “on” position, the electrical circuit is closed, to the “on” position, the electrical circuit is closed, so the light can turn on. Turning the light switch so the light can turn on. Turning the light switch so the light can turn on. Turning the light switch to the “off” position creates a break in the circuit, to the “off” position creates a break in the circuit, to the “off” position creates a break in the circuit, turning off the light.

Plastic, on the other hand, does not conduct electricity. Anything that does not conduct electricity is called Anything that does not conduct electricity is called an insulator. When an insulator blocks the flow of an insulator. When an insulator blocks the flow of an insulator.
