How to Make a Lemon Battery

Hank shows us another SciShow: Experiment! This time he's tackling what may be the most cliche, well-known and misunderstood experiment of all time: the lemon battery. The take home message in this one is: the electricity is NOT in the lemon. Just that delicious juice.

When life gives you lemons, make a crude electrochemical battery.

Fun fact I CAME here after my teacher send us this link for online class

This video is awesome! Best explanation of the lemon battery I've ever heard. It's only the second one I heard, but it's the one I needed.

Thanks for the fun revision Hank! I have a chemistry exam on saturday that has a section on electrochemistry, this definitely made my study slightly more fun.

This is actually the best explication of this experience I've ever heard. Thanks a lot!

Knowledge is a wonderful thing to share. I do love all of these videos.

I made this in 6th grade! Turned out to be a great experiment. I can't remember how many lemons it took to get a good reading. But I definitely recommend this to anyone.

I have a state science fair tomorrow. This is going to help me a lot!! Thanks Hank!!

Wow I have been into electronics all my life and that was the best explanation of how a battery works that I have heard. I know some might have to watch it twice because of the speed but some people are slow .

This science has been around for quite awhile. I personally use a watermelon as a car battery.

you are the best man I've ever met and you make a lot of great videos for science project

@scishow I really wish I could understand this more intuitively. I think a diagram would've been useful for this episode. Thanks as always!

I remember doing a science experiment on lemon batteries. I don't know why but I was really interested in it. It is good remembering how to do it!

I will be performing this experiment with my daughters this weekend. Thank you for your time to explain all this! You rock!

It took me ages to find a science project and thanks to this I found one

When I saw mark rober’s 1000 lemon wall I was pretty much positive it doesn’t matter if you do a million lemons or 10 as the electricity isn’t in the lemon, thank you for confirming this and your explanation was very eloquent. Great video

thanks, i was miffed that this wasn't mentioned in the video, even though it was a rather critical aspect of the change to the experiment.

Can you not talk so fast? I almost understood nothing.
