Gold Leaf Electroscope in Flask – Electrostatic Demonstration (KS3+)

The Gold Leaf Electroscope in Flask is a classic and reliable device used to detect and demonstrate electric charge. Designed for KS3 and above, this electroscope consists of a clear glass conical flask fitted with a secure rubber bung that supports a central brass rod with an attached strip of gold leaf. Its enclosed design protects the delicate gold leaf from air currents, ensuring accurate and consistent results during demonstrations.

This traditional electroscope allows students to observe how the gold leaf diverges when the brass rod becomes charged, providing a simple yet effective visual representation of electrostatic principles. Ideal for teacher demonstrations or student investigations, it offers a clear and engaging introduction to the behaviour of electrical charge.
