Science correspondent Allan Blackman looks at a new study which has found the skin of blueberries don't actually have a blue pigment - instead, it's their natural wax coating that gives it a blue appearance. He'll also talk about how US researchers drew inspiration from chameleons to develop a technique to 3D print multiple colours from a single ink. And could bananas be a solution to the plastic waste crisis?
Allan Blackman is a Professor of Chemistry, School of Science, Auckland University of Technology.
