Wimshurst Machine, Superior
This traditional electrostatic charge generator consists of two parallel transparent discs supported on rigid uprights. Each disc has a number of radial aluminium segments and are driven in opposite directions by hand wheel and belt. The electrostatic charge on aluminium segments is collected by combs mounted on either end of the discs and stored in the two leyden jars. When the potential difference between the jars is sufficiently high. A spark will flow between the adjustable discharging spheres.

Wind Power Demonstrator
This wind power generator can be used to demonstrate the generation of electricity by a wind-powered turbine. Wind produced by the hand-cranked fan subsequently turns a second fan connected to a generator. When the fan rotates, it produces electricity and lights up a small bulb and a voltmeter. Instructions included.

Wire Testing Clamps
This device provides an effective and very simple clamping system for testing the strength of the ductile wires such as copper, sewing threads, fishing lines and human hair etc. The material is clamped between the washers with the help of a wing nut clamp and the wire is routed through the holes provided in the clamps. The strength is checked by attaching one of the clamps to the clamp provided in the laboratory and loading the lower clamp with slotted weights. A maximum of 15 kg of weight can be hanged. Supplied without weights.
