procedures for potato power clock

Materials needed:-

2 potatoes, LCD watch movement with its protective cover, 2 zinc an copper plates, wires

Step 1:

Connect the black wire form the LCD watch which is the negative side to one of the zinc plates by carefully threading the wire's exposed metallic end through the hole on the plate.

Step 2:

Repeat step 1 with the red wire which is the positive side.

Step 3:

Assemble a "connection pair" by connecting the other pair of copper and zinc plates with a connection wire.

Step 4:

Once all the components are connected, pierced the plates into the potatoes. each potato must have a copper and zinc plate.

Theory:-

There are universal standards for positive and negative terminals. the positive terminal is always the red coloured wire whereas the negative terminal is always black. Always connect the negative terminal to the zinc plate which is more reactive than copper and the positive terminal to the copper plate which is less reactive than zinc. it is important that the exposed wire and the plate touch.
