Fluid choreography: Simple food coloring droplets do complex dance between science and beauty

By April Gocha / March 13, 2015

Stanford University researchers have solved the science behind an incredible yet simple phenomenon—food coloring droplets, when plopped onto a clean glass slide, move and dance as if they’re alive.

Prince Rupert’s Drops

By / April 9, 2009

A beloved classroom demonstration in materials science. The residual stress within the drop gives rise to unique properties that every demonstrator likes to demonstrate: The drop can be hammered on the fat end without breaking, but disintegrates explosively if the tail end is even slightly damaged.

Video of the week – Prince Rupert’s Drops

By / December 18, 2008

Again, we  present another beloved classroom demonstration in materials science. This one is a non-intuitive display of surface tension, residual stress, interior tension, potential energy and tempered glass. To create a Prince Rupert drop, molten glass is dropped into cold water. The glass rapidly forms into teardrop shape with a extended, fine tail. The material…
