Fat Brain Toys Air Toobz Expansion Pack – Air-Powered STEM Building Toy for Kids 3+

Turn a simple breeze into a curious, hands-on science session with the Fat Brain Toys Air Toobz Expansion Pack. Designed for kids aged 3 and up, this add-on invites little engineers to explore airflow, geometry, and cause-and-effect through modular tubes, colorful connectors, and playful foam balls. It’s a hands-on way to spark inquiry, experimentation, and joyful discovery during playtime.

What’s inside and how it works

The expansion pack is built to broaden existing Air Toobz setups. It adds more pieces to create longer, more intricate networks that channels air from a kid-safe turbine (sold separately) through a maze of tubes. The result is visually engaging and sonically satisfying as foam balls whirl along the paths with a gentle whoosh of airflow.

• 6 transparent 12-inch tubes for extended builds and varied layouts
• 6 transparent orange corner tubes to shape modular turns and corners
• 12 easy-fit connectors to secure creative configurations
• 10 colorful EVA foam balls to test airflow and motion

Expand, experiment, and imagine

With this expansion, curious kids can double the potential length of their Air Toobz projects and explore a wider range of configurations. The additional tubes and connectors invite endless possibilities, encouraging playful problem-solving and spatial thinking as children design new routes for air to travel.

• Double the length of your current Air Toobz build for bigger, more complex experiments
• Foster creative thinking as kids test different paths and observe how airflow changes outcomes

Learning through play

Beyond fun, the set supports foundational STEM ideas in a hands-on way. Kids can observe cause-and-effect as balls move through the tubes, compare how different layouts affect motion, and practice fine motor skills while connecting pieces. This expansion is a thoughtful complement to any Air Toobz collection, turning casual play into exploratory sessions that feel approachable and engaging for young learners.

• Supports spatial reasoning and basic physics concepts through play
• Encourages experimentation with iterative design and problem-solving

Important note: The Air Toobz kid-safe turbine is sold separately along with other accessories, including the charging cord. This expansion pack focuses on the modular tubes, corner pieces, connectors, and foam balls needed to extend builds and diversify play. It’s a great add-on for families and classrooms looking to grow a hands-on airflow experience without overloading a single kit.
