Whiz is a spinning top with configurable whistle modules which allow the sound which the spinning  top generates when in motion to be modified.  Whiz comes with a handle which allows a string to be wrapped around the top to allow for high speeds to be more easily reached. This could be manufactured using 3-D printing with the modules possessing a higher infill in order to push the mass to the outside of the object to preserve momentum longer. This toy would teach children about airflow and the noise it can generate  as well as conservation of momentum and how these both can be affected by different factors.
