floating using terminal velocity

  The terminal velocity is related to size, shape and density. A sheet of lead can float in a light up current if beaten thin and shaped properly. It does not have to rotate.

  I'm having difficulty connecting the phrases "float in mid air" and "has a constant velocity."
  Aren't they mutually exclusive?

  It is the differential velocity that matters. In a thermal (or in any medium the object is falling), if the upward velocity matches the terminal velocity the object appears to float in a fixed position.

  that is it then can we really make a very light object of larger diameter to float

  Not quite. Every heavier than medium object has a settling velocity. If it is lighter than it will have rising velocity. There has to be a counter velocity like a thermal up current or a thrust mechanism to overcome this.

  so precise calculations and tolerance to external impacts have to be seen before we can apply it
  
  
  thanks sir
