Why might a person not be able to see coloured ink on a whiteboard?

from Question of the Week, from the Naked Scientists · host Dr Chris Smith

Plus, we ask which is worse for the environment - a few weeks of volcanic eruption or a few weeks of aviation. Like this podcast? Please help us by supporting the Naked Scientists
