Vanishing Charm

Evanesco (meaning "to vanish" in latin) is the incantation for the spell used to make things vanish. This spell was most notibly used in Harry Potter and the Order of the Phoenix, once during Harry's stay at Number 12, Grimmauld Place when Bill Weasely made his parchment (Harry presumed it looked like plans for a building) vanish. Professor Snape had used this during Potions toward the beginning of the fifth year when Harry's potion was ruined and made it vanish. Hermione had also used this later in the year when she thought Harry was done with his potion (he wasn't, due to the fact that his potion-filled bottle had shattered)and had made it vanished, to Harry's dismay.
