Wind Fidget Spinner

This top can be spun manually, but instead of relying on your fingers you can instead employ the principles of science. Direct a steady stream of air downward onto the top, and it will spring into motion! Enhance the airflow with a straw for a more focused effect, and it will continue spinning as long as you keep blowing. Modeled after wind or water turbines, this top offers an engaging lesson in aerodynamics and gyroscopic stability. Enjoy it "freestyle" on your desk or place it on its magnetic storage case. For an added experiment, suspend the top upside down and propel it with your breath! Whichever method you choose, this top promises an awe-inspiring demonstration. Approximately 4 cm (1.5") in height. Colors will vary.
