Van de Graaff Generator Classroom Kit, 400,000V

This Van de Graaff generator is capable of producing 200,000 to 400,000 volts depending on humidity levels, making it suitable for classroom demonstrations of electrostatic principles. The unit features a 9-inch metal dome, a removable discharge wand (4-inch diameter), and an assembled base with internal rollers, belt, and brushes. Overall dimensions are approximately 24 inches tall with a 9-inch by 10-inch base, and typical discharge arc length is 2 to 8 cm. The kit includes interactive accessories: a dancing balls cylinder, spiked arm wheel, oscillating pith ball (Faraday's pail), long-hair brush, plastic comb, and neon tester. These components support demonstrations of charge conservation and transfer, the triboelectric effect, conductors versus insulators, and ionization and discharge. A comprehensive instruction manual with assembly guidance, troubleshooting tips, and student activities is included.
