Silk Cloth Square for Static Demonstrations, 12 x 12" Material_Bristle water vascular system

water vascular system

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

dramatizing Coulomb repulsion and charge distribution on conductors

sized for low-current circuit work below the 1A range where finer resolution matters more than full-scale capacity

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

Silk Cloth Square for Static Demonstrations, 12 x 12" Material_Bristle water vascular systemUsed 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.
