Nadia felt an explosion somewhere and turned around to see. It was coming from Terry's Weasley's cauldron, which was spitting potion pieces everywhere. Nadia got just in time to withdrawl he wand and perform protergo at one that was going her way. Without being able to perform it everywhere, and because it was hitting other students cusing purple boils, Nadia could only think of one thing to do and tried to cover it in bands like a cauldron mummy. It was melting, then bands, so she performed more and more bands. (ooc: arg, nvm)
