Got the extra credit

One of the extra credit assignments for my sons 6th grade science class was a potato clock. I had trouble finding the individual pieces required so I ordered this online. My son was able to follow the instructions easily and put it together. He thought it was pretty cool when the clock turned on. He got the extra credit.

Product worked great out of the box. Used it for my son's science project and it did not disappoint.

Clock won't keep time!
by Pris Brutlag (1 out of 5 stars)

The clock turned on but wouldn't keep the set time after MANY TRIES. It keeps reverting to 12:00 with in seconds or minutes. My grand daughter was so excited to set up the potatoes and electrodes. When the clock lit up she was SO excited but then became VERY disappointed when the clock wouldn't maintain the time set. I would like a refund or a second clock sent free of charge.

Good, fun, educational science toy.

My daughter took a couple months before actually playing with this, but once she did she was fascinated and turned it into a science project testing all sorts of other foods and trying to determine what it is that made it work. This is an inexpensive but educational gimmick that she still plays with now.

My only concern is the wires are very cheap and break easily. Expect to have to strip them to get to more wire after they wear out, and if the toy gets any serious use expect to replace the wires completely. Fortunately that's about 50 cents of wire so not a big deal.

Our 9-yr old really liked it, but did need an adult's help

A nice project for a child and adult to do together. Our son is nine and loved the kit. We all loved that it worked (lit up the clock). Make sure your connections are secure. The only thing that I'd suggest is for the company to add a blurb about why/how it works (e.g., acid from the food/drink starts reaction with the...). I had to search online for the underlying science.

This is one of these kits that you could easily make, for cheaper

This is one of these kits that you could easily make, for cheaper, by picking up the different components at the store. I knew this when I purchased this kit, but bought this anyway for the sake of saving myself store time. I like that I can easily use the different pieces for further electricity experiments down the road.

Who! Knew! a potato had that much electrical current in it. I didn't. I bought this for my children but ended up putting on my desk in my office.

My kids used this for a science fair they had in school. They hooked one up to a potato, one apple and one lemon! They won first place in the science fair. This worked absolutely beautifully in fact the potato was still going strong and just wouldn't die! Fantastic it has everything you need

Don't waste your money

Don't waste your money. Bought one for my daughter's science fair project-the clock didn't work well. Bought a second since we were running out of time and it didn't work at all.

Perfect for science projects or safe projects with children
by Crystal (5 out of 5 stars)

This was a perfect buy to help my daughter with her science project. It was safe effective and easy to use. It's not only for the potato clock but has several other ideas for Effective science projects as well. In fact we will be using this next year in the other stated projects as well. it's a money saver and safe

This is to cute for words. it has been running for about a month and keeps very accurate time. The children in my daughters class were thrilled to watch 2 potato's supply power for the little clock...Who would have thought.
