The technology of fluidics has evolved from a variety of devices that exploit phenomena of fluid mechanics such as transition from laminar to turbulent flow and jet attachment to a solid wall.
In This experiment, a let emerging from a slit flows against to wall to which it attaches. The wall may be swung to deflect the jet through a large angle without jet attachment. A Second wall may be introduced at the other side of the jet, which may be switched from one side to the other, as is done in the fluidic switch of the type called a flip-flop.
