Wimshurst Machine

This machine produces large static electric sparks for a terrific classroom demonstration. No assembly required, simply attach the hand crank, begin cranking, and watch in wonder as the sparks fly. Instruction guide and helpful hints are included with each unit.

Unit consists of two high resistance 25cm plastic discs, with equally spaced metal sectors. The discs are supported in two rigid upright supports, rotating in opposite directions with a hand crank. Provided with a system of induced charge collecting brushes, adjustable ball-ended electrodes, and cylindrical Leyden jar capacitors for obtaining higher potentials. Produces substantial opposite charges, which are deposited in the capacitors and on the metal spheres. A rapid sequence of sparks can be generated by lowering the system capacitance (moving the metal spheres closer together).

Mounted on an insulated wooden base.

Ion Generator

Generates negative ions and blows air without any moving parts.

High voltage negative ion generator generates "ion wind" without a fan or moving parts. Wind is generated by force of ion repulsion. Similar in principle to the ion propulsion systems used by NASA in modern spacecraft. Generate negative ions for health and airborne pollution removal in small areas. Kit includes 7.5kV DC negative power supply at 400 uA, 7 ion wind tubes and mounting hardware for the ion wind generator.

High Voltage Plasma Generator

• Generates 1" sparks to handheld screwdriver
• Light fluorescent tubes without wires
• Build your own Plasma Balls
• Generates up to 15kV @ 22 KHz from solid state circuit

Solid state high voltage power supply is perfect for high voltage experiments, like Kirlian photography. The high voltage at the terminal won't electrocute you, so its relatively safe, but it can burn you, so use caution. 12 VDC 500 mA.

Negative Ion Generator

Compact negative Ion Generator cleans air impurities and provides a fountain of fresh air. These negative ions are the same type that are produced in a thunderstorm. This unit is set to 7.5kv and can operate directly from standard 120VAC. Very simple to use - just connect any AC line cord to the black and white power leads and a tremendous quantity of negative ion will be emitted by the 4 needle emitter assembly shown. Fully encapsulated module is about 2" x 1 5/8" x 7/8".
