Air Toobz is a hands-on, air-powered tube system that turns airflow into open-ended STEM play. Kids build loops, swirls and pathways with transparent tubes and easy-fit connectors, then use the kid-safe fan to send colorful foam balls soaring, hovering or cycling through their designs. The rechargeable fan features a simple dial and LED indicators to explore different airflow levels, plus an auto shut-off for safety and long-term play. Packaged with 20 EVA foam balls, multiple straight and corner tubes, a T-piece, funnel and connectors in a reusable case, this set sparks creativity, spatial reasoning and cause-and-effect experimentation for young builders aged 3 and up.
