How it works:
1. The metal
strips and potato make a simple battery that creates electricity to
operate to operate the clock. Each potato works as a device called a
electrochemical cell. It converts the chemical energy stored in the
metal strips intoelectrucal energy.Two potatoes are needed to make
electricity strong enough to run the clock.
2. A cell works
because of the chemical properties of the metals inside (in this case
the copper and zinc). The different properties cause tiny particles
charged with electricity .
(called ions) to
move between the the two strips of metal. This flow is an electric
current. The potato contains the particles that allow the current to
flow,but it stops the metals touching. Electric current also flows along
the wires between the zinc and copper strips and the clock. This
current makes the clock work.
3. The potato chip can be replaced by other fruits such as lemon, orange and tomato etc.
