Generate 200,000-volt sparks. Demonstrate the physics of electrostatics in real time.\u003c\/p\u003e\u003cp\u003eThis desktop Van de Graaff generator produces high-voltage, low-current static electricity through triboelectric charging — the same principle that creates lightning. Place your hand on the sphere and feel your hair lift as charge accumulates on your body. Bring a grounded object close and watch centimetre-long sparks jump through the air.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat you can demonstrate:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eCoulomb's law — charge accumulation and repulsion\u003c\/li\u003e\n\u003cli\u003eElectric field lines using tissue paper streamers\u003c\/li\u003e\n\u003cli\u003eFaraday cage shielding\u003c\/li\u003e\n\u003cli\u003eTriboelectric series and charge transfer\u003c\/li\u003e\n\u003cli\u003eLightning rod geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e 15cm polished aluminum sphere · 200,000V output (low current, safe to touch) · Rubber belt drive · AC-powered · Includes discharge wand and instruction guide\u003c\/p\u003e\u003cp\u003eUsed in university physics demonstrations worldwide.\u003c\/p\u003e","brand":"Golden Physics Project","offers":[{"title":"Default Title","offer_id":54140237087012,"sku":"GPP-VDG-GEN","price":89.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1007\/2879\/9524\/files\/P6-3300DeluxeVandeGraaf2048x2048.jpg?v=1780680396","url":"https:\/\/shop.goldenphysics.org\/products\/van-de-graaff-generator-electrostatic-demonstration-kit","provider":"Golden Physics Project","version":"1.0","type":"link"}
