Play with air! 2023 Toy of the Year Finalist!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 fan 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 Toobz Kid-safe fan that sends foam balls flying through a network of modular tubes Encourages spatial reasoning, creativity, experimentation, problem-solving, STEM learning Connect and arrange the tubes any way you want Accessories let you experiment with airflow and physics Fan unit features simple on/off button, large dial with LED indicators for adjusting airflow Experiment with how different levels of airflow affect movement Fan unit has a rubber carrying handle Rechargeable battery - 1 hour runtime on full speed, 3 hours on half speed Features auto shut-off after 15 minutes to prevent battery drain Includes 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 cable Packaged in a reusable storage/carrying case Plugs into a wall outlet to recharge - Recharges in under 2 hours Fan unit measures 11.5 x 6.5 x 6 inches High-quality materials and construction - Lasting durability, exceptional play experience  

You shoot, you score! A kinetic art mechanism that blends the intrigue of sophisticated machinery with the excitement of sports science. Spin the hand crank to wind up the elastic powered striker arm to launch balls through the loop system and sink them in the return basket.2 alternate builds - Copter and Pirate Ship

Create your very own animal keychain by following simply sewing instructions. Beautifully packaged in a keep safe cannister style packaging. 7.5cm x 7.5cm x 17cm 6+

Learn how you can transmit power using cams and cranks and how they can be used to convert reciprocal to linear motion. Discover how these mechanisms are crucial elements of many machines even though they are not considered as ?Simple Machines?.  Build 8 working models of cams & cranks such as a fishing crane, an oil pump, a moving figure, a moving bridge, a sewing machine and a flying eagle. You can find easy-to-follow building instructions for all models either online or in the booklet included. The booklet provides detailed explanations of the different scientific principles applied and incorporates innovative experimental activities for hands-on learning. A Quiz section is also available to challenge your newly acquired knowledge!Build an oil pumpConstruct a working model of an oil pump and find outhow different simple machines work together withcams. Are you up to oil drilling? Turn the crank and seehow everything changes position in front of your eyes.Build an eagle with flapping wingsThis model of a flying eagle is designed to flap its wings by the use of the cam and crank mechanisms. Turn the crank and discover how rotational motion becomes linear. Observe how the flapping motion is produced by the employment of linkages.Build a fishing craneConstruct a unique fishing crane and learn how the crank helps set this device into motion. Compare your model with a real life one and find out the capabilities of a crank when connected to a string for lifting heavy loads.Build a moving figureBuild a model of a moving figure that uses cams and learn how you can change the direction of motion and assemble 2 different types of cams. Play with this model and discover the properties of cams.
