Thinking of my Grand daughter** A: Yes. This is appropriate for 5 and up. Some 4 year olds too. The pieces can be challenging to push together and keep in place and the connectors can be a hazard for small children. **Q: how long is each straw?** A: 7.87 inches each straw. **Q: Does it have any instructions to start some sample projects to stimulate a child?** A: My kits did not have step-by-step instructions, but they did include a card and pamphlet with images the child can look at and copy to make. **Q: Can you pour water to show kids how water travel in pipe ?** A: The Straws are open like regular straws. just more rubbery, so water would pour through them, they are solid colors so you wouldn't see the water pouring through them but see the end result. We just used them for building different shapes. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by A***. on February 8, 2026* ### ⭐⭐⭐⭐⭐ Review *by K***S on November 15, 2020* ### ⭐⭐⭐⭐⭐ Review *by M***A on December 18, 2025* ## Frequently Bought Together - RAINBOW TOYFROG Straw Constructor Toys Stem Building Toys - 300 Pcs Straw Connectors Toy Building Sets Kids Toys for Boys & Girls - Straw Building Set Engineering Kit - Autism Toys STEM Games - Brain Flakes 500 Piece Set, Ages 3+, Interlocking Plastic Disc Toy for Creative Building, Educational STEM Learning, Construction Block Play for Kids, Teens, Adults, Boys, and Girls - Learning Resources STEM Explorers Pixel Art Challenge - Math Puzzles, Pattern Blocks, Creativity for Kids Sensory Bin, Arts and Crafts, Math Manipulatives, Building Toys, Montessori --- ## 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.vu/products/30497893-straw-constructor-toys-stem-building-toys-300-pcs-connectors-toy](https://www.desertcart.vu/products/30497893-straw-constructor-toys-stem-building-toys-300-pcs-connectors-toy) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-08*
