Creator Lemon Clock

When life gives you lemons… make a clock! Construct this timber clock and watch as a lemon powers the LCD screen. This fully functional clock uses zinc and copper to draw power. To get more scientific, the lemon juice is an acidic electrolyte that is connected to a circuit with the zinc and copper. Illustrated instructions will guide you through the process. If you want to get fancy, you can even paint your timber pieces in colours you love before you start. May we suggest, yellow? Originally designed for the purposes of education about electrolytes and electrodes the lemon battery is a great way to illustrate the chemical reaction of oxidation and reduction.
