Flying-free glass is an innovative, South American-born way of flying.
There, plastic bags filled with water are hung in open windows and doors, in order to keep annoying insects away.
The flying-free glass uses the same principle, but with a shapely, decorative glass container.
Simply fill this with water so that it can produce various optical effects.
On the one hand, the water acts like a prism and breaks the light into its individual colors (rainbow effect), on the other hand it enlarges like a magnifying glass through the drop shape.
Flying irritates the head-standing, enlarged representation of the objects lying behind the glass.
When flying by, it looks as if something is moving.
That's why the fly tries to escape.
