Touching the electrodes to your tongue closes the circuit and allows an small electric current to flow. A single lemon produces about 7/10 of a volt of electricity. If you connected two lemons together, you can power an inexpensive digital watch (uses about 1.5 volts). (Use a length of thin, flexible wire to connect the silver wire of one lemon to the copper wire of the other lemon. Then attach thin wires from the other two wires in the lemons to where a battery's positive and negative poles connect to power the watch.)
Creating a battery from a lemon is a common project in many science text books. Successfully creating one of these devices is not easy. Batteries consist of two different metals suspended in an acidic solution. Copper and Zinc work well as the metals and the citric acid content of a lemon will provide the acidic solution. Batteries like this will not be able to run a motor or energize most light bulbs. It is possible to produce a dim glow from an LED.

Important information about LEDs: LEDs are designed to work at very low voltages (~ 2V) and low currents. They will be damaged if connected to batteries rated at over 2 volts. LEDs require resistors to control current when used with batteries rated at over 2 volts. Lemon batteries produce low current. It is OK to connect an LED to a lemon battery.
At best we can use several lemons to
If a science book contains the lemon battery bulb-lightning experiment, it means that the author never performed the experiment to see if it works.
The lemon battery project requires almost no advance setup. Just gather the above material, strip the insulation off the wire and use the sand paper on the wire and nail ends just before performing the experiment.
You can even use this trick to let your lemon battery runa low-voltage buzzer or turn a small motor (look for "solar cellmotors" from various mail order suppliers or Radio Shack.) As with the bulb, you mustcharge up the capacitor for many minutes, then use it to run your bulb ormotor for a few seconds.
It's not an ideal experiment, and it's hard to explain how work.
