DESCRIPTION:Smectic liquid crystals are slimy organic liquids that form su
 bmicron thick suspended films\, rather like soap bubbles.  These films are
  nearly perfect two-dimensional liquids\, with uniform thickness down to t
 he molecular scale.  I will describe fluid mechanical convection experimen
 ts carried out in smectic films which are forced electrically. With gentle
  forcing and an applied shear\, we can produce a pattern of vortices that 
 exhibits interesting nonlinear dynamics.  With strong forcing\, we can stu
 dy the scaling behaviour of turbulent convection.
