It has been also in the media for long time as the main explanation for flying saucers.
But many toys and drones have been made around it.

Tom has used this printed impeller to generate lift and thrust for his Coanda Effect Quadcopter.
Instead of using traditional propellers, he decided to 3d print his own impeller from different designs.
