8.Potions

It was Bellatrix's and Rodolphus's first potions lesson.While Bellatrix was doing very well, Rodolphus wasn't having much luck.
They were making a boil cure potion, which was supposed to be very simple. Bellatrix was already adding the porcupine quills.Rodolphus was still crushing his snake fans.Quickly,he threw the crushed snake fangs into the cauldron,followed by the horned slugs and finally the porcupine quills.
He heard a hissing noise and clouds of green smoke came from his cauldron.People around him began coughing and as the smoke cleared,he saw a smiling Bellatrix standing by the furious potions teacher.
