Pith Balls

PIRA: 5A20.20

Materials: Ping Pong Balls, Metallic Paint

These balls can be used for a variety of demonstrations within electrostatics. They are covered in metallic pint, so they have the ability to pick up charge and will be attracted or repelled by other objects depending on their charge. Ex. The balls can pick up negative charge from the vandegraff then hold it over the vandegraff and if it is on a string it will bend the string like someone is holding the ball.
