Product Details

Like paw prints in the snow, precisely timed sparks are created by the generator to leave a permanent series of tracks on paper. Interval measurements can be done any time after completing the experimental run. Set the spark generator on one of eight frequencies (60, 30, 20, 15, 10, 5, 2 and 1 Hz) at a voltage of around 30 kV. On an air track, the spark paper attaches along the track’s bottom edge. A short piece of wire attaches to the glider with an insulated nylon screw. A trolley wire stretches between the end stops with insulated hardware. The spark jumps from the wire on the glider, then through the spark paper to the grounded track, leaving a mark for each pulse. Includes 1.2-m alligator-clip connections. Controlled by a manual pushbutton trigger. Dimensions: 9.5 cm × 26 cm × 22 cm.
