We’re going to power our electricity needs with renewable energy! Well…p’raps not!
Here’s another experiment in the continuing series! This time, R and I made a battery with lemons, galvanized nails and one pence pieces.
See this link which shows how. We tried to get an LED to light, but you had to peer very closely so see any glow as it was so faint. What we did manage to do was get the LED to flash by clamping a capacitor across the ‘terminals’ of the battery and then touching the LED across it every few seconds.
My youngest daughter dipped her finger into some spilled juice, so then she and I cleaned up and made real lemonade. Yum, bonus result!
