120mL Glass Alcohol Lamp with Metal Cap and Fiber Wick Biology_Microscopy Used to crank a row

Used to crank a row of 16 cam-driven rods through a moving sine wave

this demonstration electroscope detects and visually quantifies the magnitude of static charges

Engineered to expose both AC and DC generation on a single hand-cranked apparatus

tightened with an Allen wrench for constructing lattice frameworks on laboratory benches

fanning apart visibly when a charged rod approaches to demonstrate electrostatic repulsion and induction
