Extract from Harry Potter and the Goblet of Fire

‘Bubotubers,’ Professor Sprout told them briskly. ‘They need squeezing. You will collect the pus –’

‘The what?’ said Seamus Finnigan, sounding revolted.

‘Pus, Finnigan, pus,’ said Professor Sprout, ‘and it’s extremely valuable, so don’t waste it. You will collect the pus, I say, in these bottles. Wear your dragon-hide gloves, it can do funny things to the skin when undiluted, Bubotuber pus.’

Squeezing the Bubotubers was disgusting, but oddly satisfying. As each swelling was popped, a large amount of thick yellowish green liquid burst forth, which smelled strongly of petrol. They caught it in the bottles as Professor Sprout had indicated, and by the end of the lesson had collected several pints.

‘This’ll keep Madam Pomfrey happy,’ said Professor Sprout, stoppering the last bottle with a cork. ‘An excellent remedy for the more stubborn forms of acne, Bubotuber pus. Should stop students resorting to desperate measures to rid themselves of pimples.’

‘Like poor Eloise Midgen,’ said Hannah Abbott, a Hufflepuff, in a hushed voice. ‘She tried to curse hers off.’

‘Silly girl,’ said Professor Sprout, shaking her head. ‘But Madam Pomfrey fixed her nose back on in the end.’
