You shoot - you hit! Introducing the new VEX® Hook Shot Ball Machine from HEXBUG® - a motion machine that combines the excitement of a sophisticated machine with the excitement of sport. Turn the hand crank to cock the elastic striker to shoot balls through the grinding system and into the basket. Once constructed, the VEX® Hook Shot Ball moves 1 ball per second (8 balls included) in an endless loop. HEXBUG® specifically promotes engineering understanding using STEM learning principles, and in doing so, hopes to inspire future generations of engineers and designers through creative play. Children learn important scientific principles such as the theory of motion and potential energy. Collect and connect all VEX® Ball machines or give your VEX® Hook Shot Ball machine a powerful drive with the VEX® Motor Kit (Art. No.: 1413758).
