The dazzling blue colour of copper sulphate makes it visually one of the most appealing crystals. Here, we create a saturated solution of copper sulphate by dissolving it in heated water, till no more dissolves. We then suspend a string (substrate) into this solution and let it be there for several hours and days. Filter out the solution on a daily basis to remove some impurities, which may hinder the formation of crystals. Did you manage creating a sapphire gem-like crystal on your string? Bonus: Fire Extinguisher. Make a hole in a plastic bottle cap and fix a bendable straw. Wrap given soda in a tissue paper and put it in the bottle with vinegar. Shake the bottle and point the straw to a burning flame. Does it turn off? ThinkTac TACtivities use simple and accessible materials to develop scientific temper by observing physical realities, testing, hypothesising, questioning and analysing. Variations are designed to encourage tinkering, creating opportunities to apply logic, problem solve and think critically and creatively. All TACtivities are linked to the curriculum and help understand underlying science concepts, assisted by topic guides and videos. Our App provides access to step-by-step videos, interactive simulations, variation videos, topic guides, topic videos and exploration games for most TACtivities. ## Features - A string is suspended in a saturated solution of copper sulphate. Over time (several hours to days) crystals start forming on the string. By routinely filtering out the solution and re-suspending the string in it, one should be able to grow large, blue crystals of copper sulphate. - The kit contains copper sulphate power, test tube, and step-by-step guide for Hands-on learning. - Login to our forums for videos, variations, support and mentoring on further exploration. - Designed to reinforce science concepts while honing creative, critical thinking and problem-solving skills. Curriculum alignment – ICSE V (Solids, Liquids and Gases) ICSE VIII (Water – Crystallisation of Water) and CBSE VIII. - Also included in the pack - bonus TACtivity of Fire Extinguisher. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07H7J7CNM | | Age Range Description | Kid | | Brand | ThinkTac | | Colour | Multicolor | | Customer Reviews | 5.0 out of 5 stars 1 Review | | Educational Objective | Critical Thinking | | Manufacturer | ThinkTac | | Material | Crystals,Copper,Crystal | | Minimum Recommended age | 96.00 | | Operation Mode | Manual | ## Images ![Grow Copper Sulphate Crystals (DIY Science Kit) - Image 1](https://m.media-amazon.com/images/I/31nK3EPxy2L.jpg) ![Grow Copper Sulphate Crystals (DIY Science Kit) - Image 2](https://m.media-amazon.com/images/I/71QWwZj6T4L.jpg) ![Grow Copper Sulphate Crystals (DIY Science Kit) - Image 3](https://m.media-amazon.com/images/I/51f+EaQwxbL.jpg) ![Grow Copper Sulphate Crystals (DIY Science Kit) - Image 4](https://m.media-amazon.com/images/I/51Qr+J9XXnL.jpg) ![Grow Copper Sulphate Crystals (DIY Science Kit) - Image 5](https://m.media-amazon.com/images/I/71wsUcm-dVL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by V***A on 30 January 2019* --- ## 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.pl/products/83228906-grow-copper-sulphate-crystals-diy-science-kit](https://www.desertcart.pl/products/83228906-grow-copper-sulphate-crystals-diy-science-kit) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-28*
