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 should be 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 angle.
