You May Know Potatoes As A Good Source Of Potassium,
But Did You Know They Can Be Used To Power An Alarm Clock.
The Two Potato Clock Allows You To Generate Enough Electricity To Run A Digital Clock Using Potatoes Just Push The Zinc And Copper Electrodes Into The Potatoes Causing An Oxidation/Reduction Reaction That Is Converted To Low Voltage.
The boards are absolutely fabulous. I let my grandson actually use a pencil to trace the letters. He was really struggling to write. It is amazing how fast he is coming along. It took a long time to get to me, but definitely worth the wait.
would definitely recommend - happy with speed of delivery and very happy with quality of finish.
These tracing boards were exactly what I was hoping for for my four-year-old!
