Is purple rain possible?

Saffron FOSTER

Abstract


Purple Rain, as sung by Prince could be possible in reality. Throughout history, ‘blood rains’ have been seen where rain appears red. The knowledge of this phenomenon allows a method to be devised in order to obtain purple coloured rain. The suspension of a potassium permanganate powder within the atmosphere seems to be the most practical and safe way to produce this ‘purple rain’ effect.
