The classic high-voltage generator as a fully functional cardboard kit Non-hazardous thanks to constructive current limitation
For many it is the strongest, for some the only reminder of their physics lessons: two rotating plates with metal segments, two rods with balls at the ends and two silver-plated bottles, assembled to a machine. When the cranking was done, bright and loud lightning bolts suddenly shot from one ball to the next, and the air smelled slightly of ozone. And when a courageous classmate let himself be connected to one of the poles, his hair stood on end. Do you remember? (Just to refresh: That was the chapter “Static Electricity and Influence”).
For a long time, Wimshurst machines, invented around 1880, were the only reliable high-voltage sources required for X-ray machines. Today, artfully restored, they can be found in museums such as the Mathematisch-Physikalischer Salon in the Dresden Zwinger and some in school collections, where they enable important experiments on electrical charges.
Electrifying machines of a similar design already made their way into the fine salons 200 years ago, where society amused itself with experiments such as the “Electric Kiss”: the gentleman who dared to give the charged lady a kiss immediately received a blow. Now and then we today get such “kisses” when we get out of the car in summer after a long drive.
Despite the up to 70,000 volts, even an unintentional contact with this Wimshurst machine is harmless: The capacity of the two Leiden bottles, i.e. the capacitors, is such that the strength of discharges remains far below the limits set by the authorities.
A highly exciting pleasure in the truest sense of the word for all those who have always wanted to make it really crack, and at an unbeatable price!
