Easily and safely discharges an electrostatic generator. A polished aluminum sphere, 10.5 cm in diameter, is mounted on a 40 cm insulated lucite rod. A flexible wire lead has a banana plug at one end and a clip on the other for attaching ... more

Our most economical mini Van de Graaff generator. Use this junior model of the Van de Graaff generator for numerous electrostatic experiments and displays. This 34 cm mini version produces 75,000 volts and delivers sparks up to 10 cm in length ... more

This may be used as an isolated charge sphere or may be grounded to the base of the generator, thus intensifying the arc discharges by the addition of capacitance. A flexible grounding lead with banana plug and alligator clip is included. ... more

A great way to demonstrate basic principles of electrostatics. The metallized ball, when first brought near the dome, is attracted by induction until it touches. It is immediately charged to the full dome potential and repelled. The ball then ... more

When connected to a high voltage electrostatic source, sparks will jump across each of the gaps in the metal foil pattern. This is an impressive demonstration, especially in a darkened room. Intended to be hung from the clip at the top of the ... more

Small, lightweight balls are suspended both on the outside and inside of a short length of metal tubing. When the cylinder is charged through the top electrode, the balls touching the outside surface will be repelled but the balls inside will ... more

When brought near the dome of a generator, the whirl spins rapidly in a direction that is away from the points. The electrons escaping from the dome to the spokes ionize the air at the sharp points. Since the spokes are continuously charged ... more

When small bits of aluminum foil, pith, or vermiculite are placed in the cylinder and the upper plate is brought near an operating generator, the particles will bounce rapidly. They are first attracted to the upper plate but, after touching ... more

The electric plume has a number of colored ribbons attached to a vacuum cup. When mounted on the dome of a Van de Graaff generator, the ribbons will slowly acquire a charge, even though they are normally thought of as insulators or non-conductors ... more

This is a glass tube filled with neon gas and is similar to a section of ordinary neon sign. When held and pointed at the dome of the generator, the current will light the tube a bright orange. Neon is used, as it is the easiest gas to excite ... more

A device for static measurement of electric field strength and voltages. Mounted at a short distance in front of a star-shaped measuring electrode is a modulation impeller, of the same star shape, and connected to ground. The charges infl uenced ... more
