Flask-Type Electroscope – Static Electricity Demonstration Apparatus
Explore the fascinating behavior of electric charge with this flask-type electroscope, a classic apparatus used in homeschool and classroom physics labs to detect electric charge and determine polarity. This device allows students to visually observe how electrical charge affects conductive materials, making abstract electrostatic concepts easy to understand.
The instrument consists of a 250 mL Erlenmeyer flask fitted with a plated metal rod that passes through a rubber stopper and ends in a rounded metal knob. Inside the flask, a pair of lightweight aluminum leaves responds to electrical charge by separating or collapsing, clearly demonstrating the presence and strength of electrostatic forces.
