Description

WIMSHURST MACHINE || The Wimshurst machine converts mechanical energy into electrostatic potential energy using a pulley system and rotating parallel plate capacitors RECREATE LIGHTNING || Capture your student's imagination instantly - recreate lightning! The Wimshurst Machine is perfect for creating visually stunning electrical sparks and discharges, making it an ideal tool for science classrooms, museums, and fairs 75,000 VOLTS || Generates Up To 75,000 Volts. With straightforward maintenance tasks, the Wimshurst electrostatic generator requires minimal skills or tools to operate, making it an excellent choice for schools and science centers with limited resources EXPERIMENT GUIDE || The experiment guide includes instructions for setting up your Wimshurst machine safely, steps for each experiment, discussion topics and activity questions for learners INCLUDED COMPONENTS || Set includes an assembled Wimshurst machine, two attached Leyden jars, one hand crank and an instructional guide with student activities This hand powered Wimshurst machine has two transparent plates that are supported by two rigid uprights and driven by a belt in opposite direction. They are heavy, high resistance plastic, with sectors of aluminum sheet.

The Electrostatic Wimshurst Generator consists of two 12" dia. circular plastic plates, which are rotated in opposite directions by a drive belt mechanism. Machine includes two Leyden jar condensers made from Corning glass and aluminum foil. The assembled unit is mounted on a sturdy ABC base. It stands 15" tall and generates up to 75,000 volts! Voltage and Current output are dependent on the humidity the machine is working in, as well as how fast one cranks. At maximum output, voltage can range up to 400,000 volts, but current is usually 10 microamps or less.

Cemented onto each disc are a number of metal foil sectors, which both generate and carry small charges of electricity to be stored in the capacitor. Each sector accumulates the charges derived by influence with the other sectors. Diagonal neutralizing brushes on the front and back distribute the correct charges to the sectors they revolve. Two additional pairs of brushes collect the accumulated charges and transmit them to the storage capacitor. The brushes are also connected to spark gap electrodes.

As the plastic discs revolve, a high voltage spark will jump between the electrodes as they are gradually brought together. Static electricity is stored in the Leyden Jar condenser until discharged. Two swinging arm dischargers with insulated handles are built-in and the unit is mounted on a wooden base. Instructions included.

Recreate lightning in your own home or classroom - capture your family or student's imagination instantly!

Common questions about buying open-box and refurbished.

Why buy refurbished or open-box?
Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $61 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.
What's the difference between open-box and refurbished?
Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.
Why use OpenBoxFox?
Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for EISCO products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.
Is it safe to buy refurbished?
Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
