You can also create a circuit with RGB LED lights, and let the LEDs emit different colors of light by changing different experimental materials to let your child experience the fun of the experiment. Advantages: Through complete the fruit battery science experiment project with kid, it can create children's imagination, improve hands-on ability, increase scientific knowledge, and cultivate scientific invention hobbies Package include: 4 X Copper sheet 4 X Zinc sheet 2 X RGB LED 1 X Electronic Clock 4 X Wires 2 X Wires with clip Remember to rinse with water after use and dry and store for next use.CHOKING HAZARD：Small parts. Not for children under 3 yrs. ## Features - 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. ## Technical Specifications | Specification | Value | |---------------|-------| | Package Dimensions | 15.29 x 8 x 2.79 cm; 32 g | | Manufacturer recommended age | 14 years and up | | Item model number | EUDAX-FRUIT-KIT | | Educational Objective(s) | Physics Teaching Model-Fruit Battery Model | | Assembly Required | Yes | | Batteries Required? | No | | Batteries Included? | No | | Material Type(s) | copper | | ASIN | B07RSGFWK5 | ## Product Details - **Size:** S - **Brand:** EUDAX - **Theme:** Science - **Age range (description):** Kid - **Item weight:** 0.03 Kilograms ## Images ![Fruit Battery Science Experiment Kit with Electronic Clock and RGB LED for DIY Home Teaching Toy, School Science Project, Education Subject - Image 1](https://m.media-amazon.com/images/I/61GMVgP76NL._AC_UL320_.jpg) ![Fruit Battery Science Experiment Kit with Electronic Clock and RGB LED for DIY Home Teaching Toy, School Science Project, Education Subject - Image 2](https://m.media-amazon.com/images/I/61GMVgP76NL._AC_UL480_FMwebp_QL65_.jpg) ![Fruit Battery Science Experiment Kit with Electronic Clock and RGB LED for DIY Home Teaching Toy, School Science Project, Education Subject - Image 3](https://m.media-amazon.com/images/I/61GMVgP76NL._AC_UL640_FMwebp_QL65_.jpg) ![Fruit Battery Science Experiment Kit with Electronic Clock and RGB LED for DIY Home Teaching Toy, School Science Project, Education Subject - Image 4](https://m.media-amazon.com/images/I/61GMVgP76NL._AC_UL800_FMwebp_QL65_.jpg) ![Fruit Battery Science Experiment Kit with Electronic Clock and RGB LED for DIY Home Teaching Toy, School Science Project, Education Subject - Image 5](https://m.media-amazon.com/images/I/61GMVgP76NL._AC_UL960_FMwebp_QL65_.jpg) ## Questions & Answers **Q: How do you get the light to show other colors? I only see red and slight green occasionally** A: The color is based on how 'strong' your fruit battery is. There is actually a grid that you can find online that tells you the acidity (or strength) of your battery based on which color you are able to get your light to shine. **Q: Is there a trick to make the light work? i tried with 2 lemons and 3 potatoes and nothing worked! the clock did work! thanks! floren** A: Need more fuirt 4 to 5 work nest **Q: How long will the clock run using an orange or other fruit?** A: We haven’t done more than a few minutes with the clock hooked up at a time. Sorry. **Q: How many volts do the leds require?** A: I don’t know the exact voltage. It must be very low. It works with a few potatoes, pineapple and some other fruits. ## Customer Reviews ### ⭐⭐⭐⭐⭐ It works but light does not work as other have stated *by A***M on Reviewed in the United States on 22 February 2024* It works but light does not work as other have stated ### ⭐⭐⭐⭐ potato projects are hard. Nice RGB LED in this kit! *by P***L on Reviewed in the United States on 31 January 2023* 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. ### ⭐⭐⭐⭐⭐ LokenClan *by L***A on Reviewed in the United States on 15 February 2024* Excellent product, service and quality for such low and satisfying price. ## Frequently Bought Together - EUDAX Fruit Battery Science Experiment Kit with Electronic Clock and RGB LED for DIY Home Teaching Toy, School Science Project, Education Subject - Sntieecr Fruit Battery Science Experiment Kit with Instruction, Potato Science Educational Kit for School Science Project, Kids DIY STEM Lab Experiments - AstroAI Digital Multimeter Tester 2000 Counts with DC AC Voltmeter and Ohm Volt Amp Meter; Measures Voltage, Current, Resistance, Continuity and Diode, Blue --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/371950531-fruit-battery-science-experiment-kit-with-electronic-clock-and-rgb](https://www.desertcart.tn/products/371950531-fruit-battery-science-experiment-kit-with-electronic-clock-and-rgb) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-20*
