I have 4 kids ranging from 3 to 10 years old and they all love it. Parts are well made and worth the money. I bought the expansion kit and I’m glad I went ahead and made the purchase. Tube pieces are easy to connect but also stay in place. Each part is made durable and tubes are very thick plastic. I was pleasantly surprised at the quality compared to most newer toys. Review: Makes the toy even bigger ! - Had the original air toobz since my sons bday had to buy the expansion, sometimes the balls get stuck but thats the only downside. Its a game multiple kids can play if you have enough balls. This expansion pack i was worried would be too long to work but it works great. The assembly is easy for an adult but my son doesnt built them sturdy enough so I have to help him or they will fall down. But its a unique beautiful sturdy toy. Teaches kids the power of the wind ! I love educational unique toys and this toy is visually beautiful. I hope they make many more expansive packs of even just the balls would be awesome. ## Features - AIR-POWERED FUN: This STEM toy is a set of extra Toobz and balls for expanding your Air Toobz builds, a kid-safe turbine to send foam balls flying through a network of modular tubes, making airflow experiments exciting for toddlers or kids 3+. - ENCOURAGES CREATIVITY: This expansion pack comes with enough tubes and connectors to double the length of your Air Toobz build giving countless ways to experiment with airflow and physics, promoting creative problem-solving and building skills. - ULTIMATE AIR TOOBZ ADDITION: Includes 6 transparent 12-inch tubes, 6 transparent orange corner tubes, 12 easy-fit connectors, and 10 colorful EVA foam balls to experiment with bigger builds. - STEM LEARNING: These toddler toys encourage spatial reasoning, experimentation, and STEM learning, making playtime educational and fun, great science kits for kids 3+. - AN ACCESSORY, NOT THE FULL TOY: Air Toobz kid-safe turbine is sold separately with other accessories, including the charging cord. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CG7DMS52 | | Age Range Description | Kid,Teen | | Best Sellers Rank | #11,649 in Toys & Games ( See Top 100 in Toys & Games ) #382 in Toy Building Sets | | Brand Name | Fat Brain Toys | | Customer Reviews | 4.8 out of 5 stars 356 Reviews | | Educational Objective | Learning | | Global Trade Identification Number | 00810074274630 | | Is Assembly Required | No | | Item Dimensions | 14 x 14 x 4.75 inches | | Item Weight | 1.77 Kilograms | | Manufacturer | Fat Brain Toy Co. | | Manufacturer Maximum Age (MONTHS) | 36 | | Manufacturer Minimum Age (MONTHS) | 36.00 | | Manufacturer Part Number | F4641EN | | Material Type | Plastic | | Model Number | F4641EN | | Set Name | Air Toobz | | Size | Medium | | Theme | STEM Education, Building & Construction | | UPC | 810074274630 | | Unit Count | 34.0 Count | ## Images ![Fat Brain Toys Air Toobz Expansion Pack - Air-Powered STEM Building Toy for Kids & Teens, Kids Building Toys, STEM Toys for 3+ Year Old - Image 1](https://m.media-amazon.com/images/I/511RpUxhPWL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Best toy!! *by K***N on January 3, 2026* This may be the best toy I have ever bought.

Better than two Switch2 games! *by E***H on January 11, 2026* I was tempted to buy the cheaper version from China that Amazon sells, and I’m glad I didn’t because the quality is unreal., especially in the world we live in where we have to throw a toy out in a year or so because it inevitablybreaks. They have played with this nonstop. My kids are 7 and 11, and this occupies them both. I had to beg them to play one of the video games because I wanted to play it. The price tag is high, but it is worth it. Make sure you spend a little bit more and get the expansion pack, because it is needed for making bigger tracks. ## Frequently Bought Together - Fat Brain Toys Air Toobz Expansion Pack - Air-Powered STEM Building Toy for Kids & Teens, Kids Building Toys, STEM Toys for 3+ Year Old - Fat Brain Toys Air Toobz, Air-Powered STEM Building Toys for Kids & Teens, Kids Building Toys, STEM Toys for 3+ Year Old --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/563681997-fat-brain-toys-air-toobz-expansion-pack-air-powered-stem](https://www.desertcart.us/products/563681997-fat-brain-toys-air-toobz-expansion-pack-air-powered-stem) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-06*
