Electricity at 240 Volts AC is used to visualize the electrical field in between two live electrodes. A rotating circle of led's was attached a DC motor suspended above water. Where the voltage gradient is high the led's illuminate. Where the voltage is almost zero the led's are off. Tap water has a reasonable high resistance to limit the led current to about 5 mA.
