Condition :     Good
Principle :   Rotational Lift 
Area of Study :  Chemistry and Physics
Equipment :   Zoom Copter.
Procedure :   Set the Zoom Copter on the launching mechanism.  Pull the string and at the same time lift the launch mechanism out and away from you.  With practice the copter is supposed to come back to the launcher.  However in the lecture rooms the air currents usually deflect the copter to some nearby point.                         NOTE:  Warn the students before doing this so they can catch the copter if it goes astray.
