Deluxe Wimshurst Machine

A strongly constructed Wimshurst-pattern electrostatic generator with oversized 12 5/8 in. dia. discs, this high-quality machine is a great performer. The rigid support pillars, machined from solid PVC and the high-quality bearings guarantee smooth running - even when the hand crank is turned vigorously. The generator reliably produces a 1-9/16 in. spark every second. 14 in. x 12 in. x 8 in. Includes activity guide.
