Arrange the tubes and connectors in any way you can imagine. Create loops and swirls. Weave them under tables and over desks. Then, switch on the turbine and let the experimentation begin...Can you make the foam balls leap from one tube to the next, or hover in mid-air, or go around and around in an endless cycle?Or, what happens when you set it to low speed vs high speed? What happens when you load the tubes with all the balls, then turn it all the way up?With hours of runtime and loads of balls, tubes, connectors, and accessories included, kids (and adults) will never want to stop exploring!Air ToobzKid-safe turbine that sends foam balls flying through a network of modular tubesEncourages spatial reasoning, creativity, experimentation, problem-solving, STEM learningConnect and arrange the tubes any way you wantAccessories let you experiment with airflow and physicsFan unit features simple on/off button, large dial with LED indicators for adjusting airflowExperiment with how different levels of airflow affect movementFan unit has a rubber carrying handleRechargeable battery - 1 hour runtime on full speed, 3 hours on half speedFeatures auto shut-off after 15 minutes to prevent battery drainIncludes 20 colorful EVA foam balls, 6 transparent 12-inch tubes, 6 transparent orange corner tubes, 1 T-tube, 1 silicone funnel, 12 easy-fit connectors, 1 fan unit, charging cablePackaged in a reusable storage/carrying casePlugs into a wall outlet to recharge - Recharges in under 2 hoursFan unit measures 11.5 x 6.5 x 6 inchesHigh-quality materials and construction - Lasting durability, exceptional play experienceAges 3 and up.
