notes: label: Description (Brief)
content: An electrostatic spiral demonstration piece with wooden base, 1" diameter glass tube with internal foil spiral, brass contact cap and base ring. "N1E8", painted on base. An electrostatic charge from a generating machine or a Leyden jar is applied to the top contact. A spiral of foil dots line the inside of the glass tube. As the charge passes through the foil spiral to the grounded base ring, sparks jump the minute spaces between the foil dots creating a visual effect.
