Copper and magnesium bars

1. Attach a pair of copper and magnesium rods with a connecting cable as shown in the picture.

Carefully screw in exposed metal cables through the hole in the bar. Gently rotate the wire to secure it to the rod. Cover and secure connection with transparent decals.

1. Connect the black (LCD) clock cable to one of the magnesium bars. Then connect the red cable from the LCD (positive) clock to the copper bar. All components are now connected.

1. Insert the copper and magnesium bars into the potatoes, as shown in the picture, be careful that the metal bars do not touch each other. The watch should start working.

MAKE THE EXPERIMENT

OTHER EXPERIMENTS

Put some soda in the glasses provided. Insert the copper and magnesium bars into the cups, as shown in the picture, taking care that the metal bars do not touch each other. The watch should start working.

You can experiment with different liquids like salt water, fruit juices; Or fruits such as lemon, orange, tomato, etc. The fun is unlimited

CLOCK

When the metal bars are first inserted into the potatoes, the LED display will light up and display "12:00"

Press A once. The clock will start to run. You will see that the two points in the center start to blink.

Press B twice to set the month, then press A to set the correct month. Press B to confirm and the display changes to the day setting.

Press A to set the correct day. Press B to confirm and change to the time setting.

Press A to set the correct time. Press B to confirm and change to the minute settings.

Press A to set the minutes and press B to confirm.

After the minutes are confirmed, press A once. The current time will be displayed.

SEEING THE WATCH

By default, the clock display shows the current time.

To view the date: Press A once. The clock display will return to the current time after 2 seconds.

To view seconds, press A twice. To return to the current time, press A again.

If the watch shows a weak display, try one of the following solutions:

Give it time, the signal is sometimes weak at first, but it gets stronger after a short time.

Examine metal bars if they are oxidized, use paper to remove rust.

Try to place the metal bars closer (but not touching). Driving will be best if the distance between the plates is shorter.

If there is no reaction, check all the connection points. Make sure that the connection points are correctly and securely in place. Also check that the polarities are correct. Make sure that the negative (black wires) and positive (red wires) terminals are connected correctly.

Check if the metal bars are in contact, causing short circuits, if so, separate them.

HOW DOES IT WORK

Metal bars and potatoes make a simple battery that creates electricity to run the clock. Each potato acts as a device called an electrochemical cell. It converts the chemical energy stored in the metal bars into electrical energy. It takes two potatoes to make the electricity strong enough to run the clock.

A cell works because of the chemical properties of the metals inside (in this case copper and magnesium). The different properties cause small charged particles of electricity (called ions) to move between the two metal bars. This flow is an electric current. The potato contains the particles that allow the current to flow, but it stops the contact of the metals. The electric current also flows along the wires between the magnesium, copper and clock bars. This current makes the clock work.
