Nadia looked back surprised at the Ravenclaw, with a small hint of humor behind her eyes, "I have watched muggle movies so I can tell you are right on that one. Though I do have troubles believing such a force is not magical. Nevermind on that. But there are other exploding objects you want to push away from you, and you cannot always know how to apparate, especially under 17.

"Such objects could be an exploding tuba -" she smiled at this, thinking of Musidora Barkwith especially -"or an Erumpent on their days, or just a the stinky flatulance from a dung bombs. Push it away and fast HAS to be the best way to get ride of them."
