Maybe I had defective potatoes?
Before attempting the potato experiment we parboiled the potatoes to make the electric current pass easier as well as strengthening the salt bridge. However, the light only flickered for a millisecond at best. The clock worked a lot better. Over all it was a fun experiment but not effective at lighting the bulb so it was a little lack luster, but it's probably due to human error.

My son decided he wanted to make a potato clock for his science project. We checked out a hardware store and realized we'd end up with a lot of extra things we'd never use again. So I bought this kit. It was perfect and his experiment was a success. It's pretty easy to use and the instructions were great. He was able to tell his teacher how he put it together and show her how it worked. Fingers crossed he gets an A.

I teach 3rd grade science. My students read about this is in a book and wanted to try it. I brought it in and hooked it up to four lemons. It powered the clock with no issues, but the lights did not work well. I’m not sure what the issue was but the light barely emitted a small blink and went out. One recommendation is that when you insert the clips into the large blades that go in the fruits/vegetables, you need to hammer them down or crimp them with pliers to get good contact so that they work, otherwise it’s a hot mess.

I used this to teach my kids how electricity works -- how to use it and how it is generated and why. The watch face isn't really servicable (like you can't really set the time on it since it uses flimsy switches) but that doesn't matter, it shows the concepts really well.
