dramatizing Coulomb repulsion and charge distribution on conductors

Bending and curving along its 220mm length

and troubleshooting exercises

Two-inch vinyl-coated fingers on this three-finger extension clamp mount to a swivel boss head fitting rods up to 18mm

supplying an inert electrode that conducts current without contributing its own ions to the cell reaction

Silk Cloth Square for Static Demonstrations, 12 x 12" Material_Bristle dramatizing Coulomb repulsion and chargeUsed to draw electrons from glass and ebonite rods during rubbing, this silk square gives friction rods a strong positive charge for triboelectric and electrostatic demonstrations.
