STEP 1

NOTE! Not suitable for children under 3 years of age. There is a danger of choking due to

small parts that may be swallowed or inhaled. Individual parts of this kit have sharp or

pointed edges or corners. Do not injure yourself! Do not drink any of the liquids used for

powering the lemonade clock.

NOTE! Only for use by children 8 years and older. Instructions are included for parents

or other supervising individuals, and they must be followed.

Save the packaging and instructions, as they contain important information.

› Two AA batteries (1.5-volt, type AA / LR6 / penlight) are required. They are not

included in the kit due to their limited storage life.

› Avoid short-circuiting the batteries. A short circuit can cause the wires to overheat

and the batteries to explode.

› Do not mix old and new batteries.

› Do not mix alkaline, standard (carbon-zinc), or rechargeable (nickel-cadmium)

batteries.

› Always insert batteries in the right polarity orientation, pressing them gently into

the battery compartment.

› Do not recharge non-rechargeable batteries. They could explode!

› Rechargeable batteries should only be charged under adult supervision.

› Rechargeable batteries are to be removed from the toy before being charged

› Exhausted batteries must be removed from the toy.

› Dispose of used batteries in accordance with environmental provisions.

› Be sure not to bring batteries into contact with coins, keys, or other metal objects.

› Avoid deforming the batteries.

› The wires are not to be inserted into socket-outlets.

Before beginning the experiments, read through the instruction manual with your

child and discuss the safety notes. Check that the lemonade clock has been properly

assembled before use, and assist your child with the experiments. Have fun with the

experiments!

Guide both digital clock wires through

the holes in the assembly board, as

shown in the illustration.

Position the digital clock on the

sloping section of the assembly board.

YOU WILL NEED:

› Assembly board with digital clock, cup for liquids,

cup lid, 2 copper sheets, 2 zinc sheets,

lemonade or lemon soda

Firmly insert both contact springs

narrow-side-down into the assembly

board. The picture shows the correct

position.

Guide the black wire from the bottom

through the hole next to contact

spring 1. Guide the red wire through

the contact board next to contact

spring 2.

When you bend the contact springs to

the side, it creates gaps in which you

can clamp the ends of the wires.

Clamp the digital clock’s black wire in

contact spring 1 and the red wire in

contact spring 2.

YOU WILL NEED:

› Digital clock, assembly board

with battery compartment, 2

contact springs

2 Copper sheets

›

2 Zinc sheets

›

Cup for liquids

›

Cup lid

›

Assembly board with battery

compartment

›

2 Contact springs

You will also need:

› Lemonade or lemon soda

› Paper towels

› Various liquids

› 2 x AA Batteries (1.5-Volt, type

AA / LR6 / Mignon)

1. Fill the two chambers of the cup with lemonade

or lemon soda up to about 1 cm beneath the rim.

This will be your battery’s conducting liquid.

2. Put the lid on the cup. Slide one reddish copper

sheet and one silver-colored zinc sheet through

the slits of each chamber.

3. Mount the cup on the assembly board as shown in

the illustration. Clamp the cup’s black wire into

contact spring 1 and the red wire into contact

spring 2.

None of the electrical or electronic components in this kit should be

disposed of in the regular household trash when you have finished using

them; instead, they must be delivered to a collection location for the

recycling of electrical and electronic devices. The symbol on the product,

instructions for use, or packaging will indicate this.

The materials are reusable in accordance with their designation. By reusing or

recycling used devices, you are making an important contribution to the protection

of the environment. Please consult your local authorities for the appropriate

disposal location.

Now your clock will start running! You will see

numbers and blinking double dots appear on

the display.

CAUTION!

Do not let the sheets touch each

other! The pair of sheets connected by the red

wire must not be inserted together into a single

chamber.

WHY As soon as the electrodes are immersed into the liquid, they

release positively-charged metal ions from the sheets due to the action of the

acids in the lemonade, getting back negatively-charged electrons in return.

These electrons are then able to move freely in the metal.

That happens in the copper as well as the zinc, but there’s an important

difference. The copper atoms are very reluctant to accept back any electrons,

while a lot of electrons collect very quickly in the zinc sheet.

Now, if you connect the two sheets, it closes the electrical circuit. The excess

electrons move from the zinc electrode to the copper electrode. Electrical

current flows!

Would you like to know what electrodes, ions, and electrons are? Then take

a look at the “Check It Out” section!
