 Super Science project Feb 08, 2010
By M. Harding
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.

Review of Potato Clock May 02, 2010
By Mother of 3
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.

Great product Nov 19, 2010
By Fred
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!

 OK for the price... Jan 01, 2011
By Bud_Dude
This simple classic demonstrates the building of a battery using nearly electrolyte source (tomatoe, potatoe, lemon, orange, apple, etc). The clock is of very low quality with poor switches and half the indicator segments were non-functional out of the box. This was readily repaired, but is typical of these low cost kits. Regardless, my son (6) and I had a good hour or two of fun together playing with this and demonstrating the principals.

ToySmith Potato Clock Review Jan 03, 2011
By TinkerDad
This was the second kit I bought from Toysmith, the first being the Dynamo Torch. I had tried to do a project like this at home, but could not find a suitable clock. I mainly purchased this for the clock, but it is nice to have the zinc/copper strips.
Overall it was what I expected from a science kit, nothing fancy, just enough to get the job done. I would recommend these products to anyone as they are inexpensive and you can reuse the parts over and over. We spent about 2 hours play with this one alone, and I have another one on order.
I wrote up a post on my blog about how my daughters and I played with the potato clock.
