the boundary layers on the surface of the main body 101 a plurality of pressure balancing holes 104 are formed through the main body 101 on one side of the bobber main body 101 the holes 104 extend throughout a distance five times the distance of the width of the cross section at the upper section of the main body 101 the number of and sizing of the holes 104 may be increased or reduced according to the width and length of the main body 101 due to the fact that the main body 101 has holes 104 passing therethrough the volume of its lower section is reduced and the center of buoyancy of the main body 101 is raised thus making the bobber more stable more particularly when main body 101 is forced to float eccentrically water will flow through the holes 104 and around the back of the main body 101 thus balancing the pressure on opposing sides the main body 101 displaces its stream lined section to face the flowing fluid and thus maintains the smallest force of resistance though there are discontinuous forces from varying directions the bobber 10 only has a rotation displacement and maintains.
