Make a lemon battery

Sep 24, 2009 02:03 AM

The lemon battery has a rich history in many elementary science classes as a great example of an electrochemical reaction.

This is not magic, or a hoax.

The nail and penny create charged poles in the fruit.

Unfortunately, filling a car with a bushel of lemons and driving cross country in an eco-friendly glow of citrus is a pipe dream.

The lemon battery is not strong enough to power a light bulb.

Nonetheless, enjoy the miracle of nature coupled with the ingenuity of man.

The next big software update for iPhone is coming sometime in April and will include a Food section in Apple News+, an easy-to-miss new Ambient Music app, Priority Notifications thanks to Apple Intelligence, and updates to apps like Mail, Photos, Podcasts, and Safari. See what else is coming to your iPhone with the iOS 18.4 update.
