Review: Perfect present. - I purchased this salt water vehicle as i was looking for something different for my 7 year old nephew. Hes loves Lego and generally building anything. This was a perfect present for him, we spent hours in building it together and he enjoyed every moment. Months down the line he still very much enjoys playing with it unlike most other toys which simply once played are put in the cupboard. The salt watery was at time hit and a miss but worked for most part. its a excellent educational toy with lots of fun building it. the delivery was very quick, build quality of the item is very good and would highly recommend it. The Review: Cool kids project - Bought to keep the 12 year old Grandson quiet on a wet day. Spent a good while building it and really enjoyed himself. Amazing how far it can go on a few drops of salty water. It’s not quick by any means but has a fair amount of torque, gets up a chunky rug no problem. Well worth the price. ## Features - 89 Piece DIY Electrolyte Car Engine Injection Moulded STEM Construction Project & Experimentation Kit - Made from Durable ABS and PP Plastic with Metal Screws and Springs that Clip and Screws Together - Works on the Principle of Ion Displacement Requiring the Magnesium Sheets, Table Salt and Water to Work - Car Is Height Adjustable with Four Wheel Drive and Engine can be Changed to Flat or V Style Configuration - Car Measures Around 14 cm by 14 cm by 14 cm when Fully Constructed | Recommended for Ages 8+ - Includes Detailed Instructions | Takes Around 1 Hour to Create | Requires Some Basic Tools ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01FZ5Y81Q | | Age Range Description | Adult | | Age range (description) | Adult | | Battery Description | No batteries required | | Best Sellers Rank | 40,919 in Toys & Games ( See Top 100 in Toys & Games ) 124 in Kids' Electric Learning Toys | | Brand | CONSTRUCT & CREATE | | Brand Name | CONSTRUCT & CREATE | | Country Of Origin | China | | Customer Reviews | 4.3 out of 5 stars 635 Reviews | | Educational Objective | STEM | | Global Trade Identification Number | 05055371513944 | | Included Components | Salt Water 4 x 4 Engine Car | | Is Assembly Required | Yes | | Item Dimensions | 22 x 18.4 x 7.8 centimetres | | Item Type Name | Battleground - Spider (Double) | | Item Weight | 0.25 Kilograms | | Item dimensions L x W x H | 22 x 18.4 x 7.8 centimetres | | Item weight | 0.25 Kilograms | | Manufacturer | CIC | | Manufacturer Part Number | 51875 | | Manufacturer Warranty Description | 1 Year Manufacturers | | Material Type | Acrylonitrile Butadiene Styrene, Metal, Polypropylene | | Maximum Age Recommendation | 99.0 | | Minimum Age Recommendation | 96 | | Model Number | 51875 | | Size | One Size | | Sub Brand | CONSTRUCT & CREATE | | Theme | Vehicle | | Unit Count | 1.0 count | ## Product Details - **Age range (description):** Adult - **Brand:** CONSTRUCT & CREATE - **Item dimensions L x W x H:** 22 x 18.4 x 7.8 centimetres - **Size:** One Size - **Theme:** Vehicle ## Images ![CONSTRUCT & CREATE Salt Water Fuel Cell Engine Car DIY STEM Build Your Own Kit - Image 1](https://m.media-amazon.com/images/I/71+kIRKTiiL.jpg) ## Questions & Answers **Q: What age is the Construct & Create Salt Water Fuel Cell Engine Car Kit recommended for?** A: This construction kit is designed for children aged 8 and over.

Months down the line he still very much enjoys playing with it unlike most other toys which simply once played are put in the cupboard.

The ### ⭐⭐⭐⭐⭐ Cool kids project *by R***R on 26 August 2023* Bought to keep the 12 year old Grandson quiet on a wet day. Spent a good while building it and really enjoyed himself. Amazing how far it can go on a few drops of salty water. It’s not quick by any means but has a fair amount of torque, gets up a chunky rug no problem. Well worth the price. ### ⭐⭐⭐⭐ Demanding Assembly but Rewarding Result *by M***N on 17 January 2022* All the parts need accurate trimming to fit well and give the freedom of motion demanded. The instructions are accurate, though minimal: insert a gear shaft the wrong-way round invites disaster! Cleaning the electrical connections is demanding: we checked the motor non-working by using a 1.5 volt AA battery which guided my son to rebuild the magnesium-saline cell. The finished job is very rewarding. My 7 year old grandson loves the way the 4-wheel drive and flexi-suspension enables the model to climb over obstacles almost its own size. We have yet to discover how to replace the magnesium sheets when they are exhausted - maybe wire in an AA battery and micro-switch? Overall, it is good fun and value for money. ## Frequently Bought Together - Construct & Create Salt Water Fuel Cell Engine Car DIY STEM Build Your Own Kit - Poraxy 5 in 1 STEM Kits for Kids Age 8-10, Science Building Project Craft for 8-13, Model Car Kit, STEM Toys for Boys Girls Age 8-12, Wooden 3D Puzzles, Birthday Gifts for 6 7 8 9 10 11 12 13 Year Old - STEM Kits for Kids Age 8-10 10-12, 6 Set Wood Building Projects Crafts Science Model Car Kits for Kids Age 8-12 5-7, Wooden 3D Puzzles, STEM Toys for Boys 7 8 9 10 12 13 Year Old Birthday Gifts --- ## 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.at/products/48242132-construct-and-create-salt-water-fuel-cell-engine-car-diy](https://www.desertcart.at/products/48242132-construct-and-create-salt-water-fuel-cell-engine-car-diy) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-07-23*
