A drop of
Budweiser, the King of Beers, immersed in mineral oil will form a beautiful
4 sided pyramid with sharp edges.Tiny
bubbles accumulate at the top of the drop acting like a buoy that pulls on
the droplet to create the growing tetrahedral shape.The bubble cluster eventually spouts off in
unison to the surface.The changing
curvilinear pyramidal shape of the beer droplet is predicted by the
Young-Laplace or Gibbs-Thompson equation.
A laser beam is
directed on various portions of the droplet surface.Some very stunning optical effects like
green laser lightning storms are created.
The tiny bubbles form a highly reflective region for a small viewing
