In the video, the propeller does not fly, because this turns around the wrong way. The solution to the problem is to reverse the motor, that is, to swap plus and minus.

The children of the Ottersleben primary school built a circuit with loudspeakers and tested it.


The pupils of the primary school Ottersleben try to make a propeller fly.
