Finally, you can play with your food in an educational and fun way! No batteries? No problem!  Explore green science and discover how to power a digital clock using potatoes! This unit is designed to demonstrate the principle of an electrochemical cell. Just push the zinc and copper electrodes into the potatoes causing an oxidation/reduction reaction that is converted to low voltage.  Try other fruits, vegetables and beverages to see what works. you'll be amazed at what you discover!

What you'll get:

• clock with wires
  
• pots
  
• connecting wire
  
• transparent tapes
  
• copper and zinc strips
  
• detailed instructions
  
• just add potatoes

Incredible Science Fun Learning Ideas:

• Hands on learning using an electrochemical cell.
• Observe an oxidation/reduction reaction.
• Compare and contrast what happens when you try potatoes versus other fruits. Chart your results.
