Wingardium Leviosa

All together now – swish and flick! Professor Flitwick teaches this charm to his first-year students – and it certainly comes in handy for our main trio. On the very day they learn the spell (and of course Hermione is the first to crack it), they find themselves face-to-face with an angry troll in the girls’ bathroom. Ron successfully uses the spell to levitate the troll’s club and drop it on his head – knocking him out and saving Hermione in the process.
