【Classroom-Safe Design】Built specifically for educational use, this Van de Graaff generator features a stable anti-slip base and fully insulated discharge wand. With microampere-level low-current output, it delivers a controlled, safe experience for both students and educators during demonstrations. 【Essential STEM Physics Teaching Tool】A core instrument for physics education, it vividly demonstrates electrostatic induction, charge distribution, and electric field lines. This turns abstract concepts into visual, hands-on learning moments that engage students and deepen their understanding of static electricity. 【High-Efficiency Electrostatic Induction Performance】Powered by high-efficiency dual rotating disks, the generator creates a strong potential difference to produce dramatic electrostatic effects, making experiments like “hair-raising” and spark demonstrations clear and impactful. 【Rugged Construction】Made from durable, wear-resistant materials, this generator is built to withstand daily use in busy classrooms and labs. Its robust mechanical design ensures consistent performance and long-term reliability, even with repeated student interaction. 【Simple Setup & Guided Operation】Designed for easy use by all skill levels, the unit comes with clear safety instructions for integration into science curriculums. Note: Students must be supervised by teachers during use to avoid electric shock. Always discharge the unit by touching the two metal balls after the experiment is complete.
