Watching air do something
Air is invisible, which makes it hard for a preschooler to picture how it pushes a ball. Windy fixes that. Fit the windsock to the end of a tube and it billows and points the moment the fan starts, so children can see the airflow before a ball even launches.
Whirly adds the surprise. This spinning wheel sits at the tube's exit and kicks each foam ball sideways as it flies out. A ball that once shot straight up now veers off and lands somewhere new. Children quickly start predicting where it will go, then move the tube to test their guess.
Cause and effect they can steer
This is where the early science thinking happens. Change the tube angle, add Whirly, take it off, add Windy instead. Each swap gives a different result, and children learn to link a change they made to an outcome they can see. That's the foundation of testing an idea, and it takes shape from around 3 years.
There's a physical side too. Pushing an attachment onto a tube end builds hand-eye coordination, and chasing the foam balls across the room gets the whole body moving. The balls are soft EVA foam, so a stray one bounces off furniture without a fuss.
The pack grows with the child. At 3, it's about watching the windsock and chasing balls. By 5 or 6, they're predicting where Whirly will send a ball, rearranging tubes to prove it and swapping attachments to compare results.
Fitting it into your set
Both attachments fit the end of any Air Toobz tube, so they slot into builds you've already made. They need the Air Toobz fan unit and tubes to work, and those are sold separately. If you're starting from scratch, grab the base set first.
Expect moderate play noise: the fan whirr plus the thud of foam on the floor. It suits solo tinkering or a group, with one child running the fan while others race to catch the balls. Small parts are a choking hazard and the set is not for children under 3. Never aim the balls at eyes or faces.
