Rainbows are magical! They’re science! And they’re magnificent! Something about an arc of dazzling colours forces you to stare—seemingly enchanted. Interestingly, the beauty of a rainbow doesn’t know age. Kids and adults alike are fascinated by the phenomenon, which was ‘discovered’ by one of the greatest scientists in history—Sir Isaac Newton. He realised that when light fell on a prism, a dispersion would occur result in emersion of different colours (7 to be exact). Enough about science. It’s time to party! Here is a guide with the best rainbow party ideas!
