Product Description
From the Manufacturer
You may know potatoes as a good source of potassium, but did you know they can be used to power an alarm clock? This kit contains a digital clock and the instructions and everything you need (except the spuds) to run it.
Product Description
7 years & up. 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.

Our 7 year old absolutely loves this clock! She is learning about energy provided by inanimate objects like potatoes. She has tried lemons and liquids with good results. Appropriate for a lesson that does not yell SCHOOL! Would be helpful for any child needing to learn to tell time.

This was exactly what we needed. Actually we only needed the clock, but it was nice to have the whole kit. Directions from the internet made it clear that you needed a particular, low voltage / current clock and there is NOWHERE to find one. My husband is an electrical engineer and he spent days looking for one with no luck (other than trying to build one, but time did not permit that).
Directions were the same as the internet, connected the clock and it worked. Our son brought it in for his 2nd grade science project and was able to explain in "2nd grade terms" what was happening. I highly recommend this product.

I needed a 1.5v clock for my son's science experiment. So I bought this product solely for the clock. It worked perfectly. The only knock on the item is the gauge of the wires from the clock to the power source are way too thin. Not sure the gauge, but they were significantly smaller that the smallest 20 gauge wire sold by the hardware store. We tested the 1.5v clock with a .8v battery, 1.4v battery and a 1.8v battery. The clock worked in every case! Great price and great fun!

Awesome educational toy, a bit better quality would make it perfect
This is fun toy! My son was amazed and didn't believe that it can work until he saw it working. Some issues worth noticing: adjustment buttons on the clock sometimes stick inside... Read more

Keeps on ticking
We are now on our 3rd week of potato-power for the digital clock that comes in the kit. If only we could power our whole house on spuds! It really a nice fun and educational toy.

My grand son loved this!
We gave this to my 7 year old grand son for Christmas and he loved it. He and Grandpa assembled it together and he was so proud and explained to us how it worked. Big hit!

Havent received it. I dont know if it is coming.
Apparently Amazon had a mailing address on file for me from years ago and it was sent to the wrong address. I was told it would be re-directed but haven't received anything. Read more

Don't pass this clock up
Love this "toy". Sure, it's educational and all that but it's so much more. It's so easy for a child to put together although a young child might need a little help. Read more
