Product Description

Finally, a chance to play with your food! -- Learn about electricity and chemical reactions in an innovative way. -- The Two Potato Clock allows you to generate enough electricity to run a digital clock - using potatoes!

Not your standard garden-variety timepiece, this unusual digital clock harnesses the power of potatoes. Safe and easy to operate, the Two Potato Clock works by capturing electricity created by a chemical reaction inside of the potato. Sure to turn heads at the office, and a great conversation starter at home, the clock never requires any batteries--only a fresh set of tubers (any variety will do) once in a while. In the event of a potato famine, substitute a number of other common household fruits and vegetables, including apples, bananas, or avocados. Instructions for assembly and clock operation are included. --Chris Burns

My 9-year-old son was awed by this clock when I gave it to him for a gift. His plan was to do a science experiment -- to see how long the clock would keep time with various objects as the power source. Ignore what the previous reviewer said, too, as he must have had a defective version. My son's clock has been running on the same potatoes for almost 6 weeks now and isn't a minute behind his atomic clock. If you're looking for something not too expensive for a science-minded kid, this is a great idea.

I used it for a college presentation and it worked great, it doesnt keep real accurate time, I lost maybe a minute over a 24 hour period, but it could have been the potatoes. Also works with lots of other vegetables and fruits.

I had a friend who had one of these years ago and I thought it was the coolest thing I had ever seen! It is nice to know that such a silly product has lasted through the evolution of electronic toys. Kids are wild about these clocks you will find them interested in science while not even realizing that they are. These spud clocks are safe, fun and kids love them!

We really like this clock, but when we received it, there were no directions. It makes for a great science fair project.

We bought this clock for our 4th grader to use as part of a science project. It is cheaply constructed and the clock piece does not fit nicely as pictured - it hangs down in the front by the wires. Having said that - it does work as stated. We have two potatoes that have been keeping time for a week. Too bad it is so over-priced for what it is.
