Snowball

A ball of compacted snow and ice often created by children and thrown at each other as a game. In the 1991-1992 schoolyear, Fred and George Weasely charmed several snowballs to hit Professor Quirell in the back of the head (unintentionally hitting Lord Voldemort as well.) In the 1993-1994 school year, Harry Potter threw snowballs at Draco Malfoy, Gregory Goyle, and Vincent Crabbe while under the Invisibility Cloak, in retaliation for the latter making fun of his friends. In Lego Harry Potter Years 1-4, Draco Malfoy makes an igloo, and uses it as a tank to shoot snowballs.
