Small fish do not shake my head.�Sardines swim straight in order to move from the main body to the tail fins without swinging the head a little.�"Wave moving ball straight ahead" that was researched and developed to reproduce this straight movement.�Vortex generator (turbulent protrusion) introduced in order to make it straight ahead.�This vortex generator is based on fluid dynamics, it generates a turbulent flow to reduce the "large vortex instability of movement" which occurs in the back, mainly used for wings of aircraft etc. .�It does not blur even if it receives water flow and resistance, it creates a stable linear movement even in the early tide, directing the natural movement of sardines.
