Wimshurst Machine, Size : 40 X 24 X 43 Cm

In a Wimshurst machine, the two insulated discs and their metal sectors rotate in opposite  directions passing the crossed metal neutralizer bars and their brushes.  An imbalance of charges is induced, amplified, and collected by two pairs of metal combs  with points placed near the surfaces of each disk. These collectors are mounted on insulating  supports and connected to the output terminals. The positive feedback increases  the accumulating charges exponentially until the dielectric breakdown voltage of the air is  reached and an electric spark jumps across the gap.  250,000 Volts. 5 Inch Sparks Banana jacks accept either banana plugs or alligator clips for use as high voltage power supply. No one can mistake a Wimshurst Machine, especially our Classic version. Our metal foil Leyden jars (capacitors) collect static and release all of the energy at once to produce mind melting and  eyeball bu ing sparks! 12 inch contra-rotating disks with metal sectors ensure electrostatic induction on demand.  Antique,1800's appearance. Features conductive plastic charge collecting brushes which  will not scratch disks. Rigid Victorian styled disk supports and beautifully vaneered wood base  make for authentic styling. Adjustable spark gap. Smaller gaps allow for more feequent sparks, while wider settings allow for long but slightly less frequent discharges. 2 Banana jacks allow  you to connect test leads - light up xexon flash bulbs, neon lamps, see electrostatic coronas  in a dark room! The perfect gift for Star Trek fans of all ages or sparking a child's interest in science!
