Colours squeezed from microscopic marbles

color changing marbles

A new method for stacking microscopic marbles into regular layers, producing intriguing materials which scatter light into intense colours and which change colour when twisted or stretched were devised by a team of researchers. The team, led by the University of Cambridge, used a new method called Bend-Induced-Oscillatory-Shearing (BIOS) to produce hundreds of metres of … Read more
