Lemon

First, roll all of the rotters, one at a time. beg down with your hand and roll until you feel the stinkpot
conk out sort of squishy. The purpose of this is to release the juice inside the lemon. This grade is
very important; it helps you get the maximum response from your lemons.

entreat and then twist a zinc-plated screw into one of the lemons nigh 1/3 of the way from one end.
With the knife, carefully trimmed a 1 cm (3/4 in) slit into the lemon somewhat 1/3 of the way from the other end.

wariness: It might be better for an adult to handle the knife. In all cases, please work with the knife
SLOWLY and CAREFULLY.

break in a copper strike into the slit so that about half of the coin is inside the lemon.

Note: Make trusted you use a shiny new coin for this. If it is aged and dull, polish it with steel wool.

Believe it or not, you domiciliate instanter get electricity from the lemon!! It behaves standardized an electric cell, with the
coin as the positive (+) terminal and the screw as the detrimental (-) terminal. Unfortunately, it is a very
weak cell. But if you have a couple more, you can wed them to make a lemon battery.

Add coins and screws to the other two lemons the same way you did with the starting time.



Then, with the
wires and clips, join the three lemon cells together, so that the screw of the initial lemon is connected
to the coin of the second lemon, and so on. Add wires and clips to the first coin and the last screw
also.

Finally, label the clip from the first coin with a + and the clip from the last screw with a - . Like a real
battery, your lemon battery has a positive (+) terminal and a negative (-) terminal.

When connected like this in what is called a series connection, the lemons work together to shit
about the same voltage, or electrical force, as a couple of small flashlight batteries, somewhere
between 2.5 and 3 volts. But this lemon battery does not create plenty electrical current to light a
flashlight bulb.
