How are hard candies created with messages written within their cores? See how this sugary treat, called ‘rock candy’ in the UK, is poured, pulled, assembled, rolled, stretched, hardened, and cut into pieces in this Discovery UK visit to Spun Candy in London. It’s a clip from the series How Do They Do It?

The magic of this ‘conversation candy’ is in the formation of the large candy letters, the proofreading of the assembled words, and the careful hand-stretching of the warm candy “so that the letters shrink from 3 centimeters tall to just one millimeter.”
