Description
- Package Includes: 4 pieces copper sheet, 4 pieces zinc sheet,1 piece Electronic clock,2 pieces RGB LED,4 pieces Wire, 2 pieces wires with clip, 1 piece English assembly instructions
- Easy to operate: you only need to prepare fruits, vegetables or drinks to assemble a battery to work with led or electronic watches, such as: apples, oranges, potatoes, lemons, tomatoes, cola, pears, pineapples, or salt solutions, etc.
- By completing the Fruit battery Science Experiment Project with your child, let your child experience the mystery of science, develop your child’s imagination and hands-on ability, and make your child more interested in scientific experiments.
- Read the instructions carefully before building the project to avoid damage to the electronic watch or to prevent the LED from working.
- Fruit selection：we suggest you use fruit with more juice, tomato will be your first choice, if you choose lemon and orange, please insert copper and zinc tablets in the same petal flesh (there is a membrane between the different petals that will hinder the transfer of electrons), as far as possible, insert copper and zinc tablets all the way into the fruit.The LED lighting effect is more visible in dim environments.

This product was a piece of junk. The experiment absolutely did not work. In addition, there were no instructions included other than a few very cryptic diagrams. Waste of money.

Disappointed that all did not work from the pkg. Arrived quickly. Was only able to do one experiment with the kids.
Neosha –
Awesome project for my daughter Science project. Easy instruction

The worse would not stay in the metal pieces. Did not work with oranges.

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.

The wire is junk and the clips don’t connect properly. The clock doesn’t work even if you directly connect to a battery..

It works but light does not work as other have stated

Excellent product, service and quality for such low and satisfying price.

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.

I bought three sets of these for my son’s science fair project, we followed the directions and despite giving off voltage it did NOT light the LED. Now mind you, I bought THREE sets, so we had THREE different lights, and 12 sets of connectors. My husband even went so far as to solder any weak connections between the metals clips and wire, still NO GO. Don’t waste your time. Go to the hardware store.

Fun project and easy to use

My grandson was having difficulty gathering the materials for his science project. This kit was the perfect solution! Worked as advertised. After all the trouble he had gone through previously without the expected results he was frustrated almost to tears. This kit made grandpa the hero!

Even with multiple potatoes in the circuit. The clock worked. So we just changed my kids’ project to “potato clock” inatead of “potato light.” Worked out just fine.

This kit isn’t enough to power the little LED lights or they don’t work whichever the case. The instructions are lacking. The little prongs won’t stay in without crimping them. The only thing that will work is the little clock. My daughter is highly disappointed.

Bought this for my daughter to use for a science project and it was easy to use and very self explanatory. Great value for its price

This kit is the one with the cool multi colored LED. The rest of the kit is so-so. No one kit has all the best stuff, get multiple kits.Potato battery notesFirst off, if your kid is going to do a potato battery science project know that this is harder than it looks. The LED lights typically require 3 volts and about 20 mA to light them up. sometimes you will get lucky with fewer milliamps, but most require 20 mA. This requires more potatoes and more wires than you might expect. Obviously, results may vary, but don’t expect this to work with 1 or 2 potatoes. It took about 12 potatoes (4 in series, 3 in parallel) for my kid’s project. Expect it to take at least 4 potatoes. Most of these kits don’t have enough wires to connect all the needed potatoes (if you use 12 potatoes as we did). I ordered two different kits, and then later 3 more of a third kit type before we finally succeeded. Also, the larger the surface area of the zinc/copper, the more power output you will get. The rectangular metal pieces seemed to have better electrical properties than the spike-shaped ones. I think they must have increased surface area.Powering a small siren/noise maker or a clock (included in some kits) uses much less power than the LED light. A small non-LED Christmas light takes about 100 mA for full brightness.Warning: The clocks in the kits are very delicate and the wires break very easily.Wires with alligator clips are better than wires without clips.One of the kits we used came with a single LEDS that flashes multiple colors. each color using a different amount of current (mA). This was pretty cool. It required about 6 to 20 mA to light up. I used my multimeter with a store-bought battery to determine how much current (mA) each load (LED light, fan, clock) used.Pro tip: boiling a potato for 8 minutes increases the power output (credit goes to Israeli Researchers)Also: You cannot charge a phone or light a large bulb from a battery. Those are hoax videos going around the internet.

I used it for a science project. Conducting electricity from fruit and it did

Our son used these for science project one didn’t work but rest worked great.

Great cheap fun experiment for kids. Easy to use and set up. I enjoyed this as an adult as did my 2,4,7 year old. My 7 year old could do this alone if he wanted to. Only thing I didn’t like is that it was just in a plastic see through bag with some tape. That’s it.
