This is a good commercial electrophorus and is similar to the student made ones you'd encounter in the static labs in the Science Joy Wagon workbooks.
Produce a strong spark repeatedly, without recharging. When surfaces are clean and the humidity is not excessive, sparks 6mm long can be produced over many days after the initial charging. The base is thick plastic with four rubber feet attached for convenient handling. The plastic material produces a strong frictional charge when rubbed with fur or other material. This charge is held for long periods. Its flatness and high rigidity also insure minimum separation and maximum induction, between the dielectric and the removable plate. The 18cm diameter aluminum plate is designed to eliminate any sharp edges which could cause leakage. This, combined with its high capacitance due to size, permits it to acquire and transport substantial charges. An insulating handle is attached. For charging, a fur friction pad is recommended, but not included. With instructions.

Ideal for a wide variety of experimental situations, a knob on top of the stopper accepts a charge. When the charge enters the flask, the aluminum leaves separate. How much the leaves separate depends on the size of the charge. There’s no easier way to teach or observe this phenomenon. The electroscope consists of a 250ml Pyrex flask with a nickel-plated rod attached to a rubber stopper.

I really like this static version of the Genecon. It allows students and teacher to generate static electricity without all of the noise and hidden elements of the Van de Graaf generator. Hand-Operated for Easy Use Now the study of electrostatics is easier to conduct and more economical. High voltage static experiments that were once impossible without the use of a Van de Graaf generator are now possible with the innovative Static GENECON. This device creates a high voltage of over 10,000 V with only a simple turn of the generating roller. Size: 22.3cm L x 25.5 cm W x 7.5cm thick; weight: 400 g.

Thrill your high school and middle school students with exciting demonstrations as impressive as Paul Hewitt's. Show sparks fly. Make hair stand on end. Illustrate how positive and negative ions attract or repel, and more. It's easy with our new low-cost Van de Graaff Generator. This hand-crank model can develop potentials of up to 200kV and produce a spark up to 3.2 inches long. Measuring 28" high with a 10" dome, it includes a variety of accessories including a 16" discharge electrode, electric plume, and the electric whirl. Best of all, it's less than half the cost of a traditional Van de Graaff generator, so you'll be able to conduct spectacular electrostatic experiments without breaking your budget.

This rugged unit will help you give demonstrations that will impress the socks off your students, or at least stand their hair on end. The variable speed generator will develop potentials as high as 350,000 volts making it possible to perform all basic electrostatic experiments on a large and spectacular scale! With sparks of 8" to as high as 12" to 15", yet a maximum continuous current of just 10 microamps, it's quite safe for classroom use. Check out the Van de Graaff accessories that will add excitement and interest to your demonstrations:
