3A20.35 - Air Cart Masses and Springs - Air Track & 2 Springs
Attach the Plexiglas bar across the air track at the midpoint. When using the spark generator be sure that there is nothing to cause a short circuit. Attach the sparking pins to the desired car. Set the car into the track, position a length of tape under the sparking pin and tape to the railing with masking tape. Practice will be necessary. Timing gates and counters may be used if desired.
