Product Overview
Flying Ball & Silver Snake
Silver Snake: It consists of a metalized ribbon attached to an insulated handle. The ribbon is cut to a point so that when it repelled by the dome, it quickly loses its charge and repeatedly strikes back at the dome. Flying Ball: Comprises a light weight metalized ball suspended through the thread, mounted on insulated handle The ball is attracted by the charged dome due to electrostatic induction until it touches the dome, it is then violently repelled.
Electric Whirl (Static Spinner)
Comprises a series of L-shaped metal spokes with arms bent in same direction, arranged radially in circular fashion and free to rotate on an insulated stand. For demonstrating the effect of electric discharge from points. Since pointed objects carry a much greater concentration of electric charges than the Van de Graaff's dome, when brought near it the whirl spins rapidly in a direction that is away from the points.
Lightning Leaper
Demonstrates that electric discharge will follow the path of least resistance, even though it is longer than a direct path. A nonconducting plate has a long metallic conductor zigzaging across it as shown in the picture. When the ends are connected to a Wimshurst machine or Van De Graaff generator, the path which the current follows is shown by sparks across the gaps in the conductor. Dimensions (w × d × h): 200 × 100 × 20 mm.
Volta's Hailstorm
With Volta’s Hailstorm apparatus used in conjunction with a Van de Graff generator, you can demonstrate Coulomb’s law qualitatively. The device consists of a chamber on an insulated base with ball terminal to attract electric charge. Also supplied is a small amount of conductive coated spheres to use in the chamber. When the ball terminal is brought near an operating Van de Graaff generator, the particles will bounce rapidly. They are first attracted to the upper plate but, after touching, are violently repelled downward, where they lose their charge upon contacting the lower plate. They are then ready to be attracted back to the upper plate, and so on.
Electrostatic Plumes, Red & Yellow
This "head of hair" is made of nylon cords attached at the top of a metal rod which spread out due to mutual repulsion when the rod is connected to a Wimshurst machine or Van de Graaf generator. The plume is well insulated and will hold its charge for some time in dry air. Supplied as a package of two in red and yellow.
Franklin's Bells
This device is named after Benjamin Franklin who famously used them to detect approaching thunderstorms. Our model consists of two metal bells on nonconductive mounts and a small conductive bell clapper hanging on a thread between them. A Wimshurst machine or Van de Graaff generator is connected to the instrument so that one of the two bells receives a positive charge and the other receives a negative charge. Slowly turn the Wimshurst machine to build up charge. When the charge is built up, the metal clapper begins to go back and forth between negative and positive bells creating a ringing sound.
