"A bomb is more than just exploding on you," Linnea interjected, "you don't want to be anywhere near it when it goes off." Linnea felt that the Slytherin should know to be careful, most Slytherins didn't like her because she's a half-blood, but she didn't want someone to be around something that dangerous and not know. "Apparating would be better, because you could get farther away, and I'm not sure what a charm would do to it....." Linnea trailed off, hoping the Professor could say how a charm would affect something as unstable as a bomb.
