Science Explained: Potato Battery

Learn how potatoes can generate electricity!

If you are a parent doing this with your child, heres a few tips. A boiled potato is 10x stronger, and purple sweet potatoes work the best. Larger and solid galvanized metal gives you more strength as well. Galvanized carriage bolts work well and are very cheap. Modern pennies are not copper anymore "since some time in the 70s I believe, but look into it" plenty of other ways to get copper though. Also in the US we teach that positive is where the bolt comes out and negative is where it returns, that is technically backwards, in other countries they teach the actual "electron flow" in the right direction. Lemons work the best as fruit, purple sweet potatoes work the best as veg, but many many other fruits and vegetables work as well. Me and my kids used just a cup of lemon juice. Currently looking for a galvanized metal sort of cup to fill and run a copper pipe down the middle of. To get more voltage, these do not work well wired in a parallel, but do great in a series.
That's about all, good luck and make some memories that your kids will value when older.

How dıd u put the coın that flat ın the potato??? Love from Turkey🦃🦃🦃

Thanks for the amazing explanation! In conducting this experiment do we still need to slice the potato into half or not anymore?:))

Why do the electrons flow from the zinc to the copper through the wire, instead of through the potato? Does the wire have less resistance?

Can we eat those potato after experiment?
