<div class="long-description"><h2>Description</h2>This large Van de Graaff generator uniquely offers alternative drive modes, either hand-cranked or motor driven. Excellently constructed, the generator reliably delivers charge and sparks 10cm long and more immediately on setting it in motion, even under high humidity conditions. In handcranked mode, the amount of charge generated can be seen to increase at higher cranking speeds, while the much faster motor-driven mode delivers a fast succession of sparks. The generator is 76cm high and features a 28cm diameter polished steel sphere, which is less vulnerable to dents and scratches than comparably sized aluminum spheres. The generator also features a built-in lamp close to the bottom of the belt that delivers a small amount of UV light when turned on. This can be seen to increase demand on the motor power. The generator comes with a range of accessories, including a discharge wand with a grounding cord, an electric plume, an electric whirl, a discharge bulb, a cord for connecting other electrostatic demonstration items, a spare charge belt and a spare motor drive belt. The generator measures 38 x 23 x 76 centimeters.</div><div class="feature-description"><h2>Features</h2><ul> <li>Produces sparks up to approximately 10 cm or more, even in higher humidity conditions</li> <li>Hand-crank mode allows students to observe how increased speed affects charge generation</li> <li>Motor-driven mode delivers continuous, rapid spark output for dynamic demonstrations</li> <li>Large polished steel sphere resists dents and scratches while efficiently collecting electrical charge</li> <li>Integrated UV lamp enhances visualization of the belt system and demonstrates energy demand effects</li> <li>Durable construction supports repeated use in classrooms and lab environments</li> <li>Includes multiple accessories for expanded electrostatic experiments and demonstrations</li> <li>Encourages hands-on exploration of static electricity, electric fields, and energy transfer concepts</li> <li>Ideal for physics classrooms, STEM labs, and advanced science instruction</li> </ul></div><div class="in-box-description"><p><strong>Includes:</strong></p> <ul> <li>1 Dual Drive Van De Graaff Generator</li> <li>1 Polished Steel Sphere</li> <li>1 Discharge Wand</li> <li>1 Electric Plume</li> <li>1 Electric Whirl</li> <li>1 Discharge Bulb</li> <li>1 Connector Cord</li> <li>1 Spare Charge Belt</li> <li>1 Spare Motor Drive Belt</li> </ul></div>
