u cant blame people for believing in magic! i mean its so well xplained and blah blah by JK. but people shudnt be stupid enuff to actually do stuff like flying a broom. i mean dint they read Quidditch through the ages, its written there that spells and charms were put on brooms to make it fly. so people shudnt attempt to fly as they do not have a wand and cant do magic. but the "DO NOT TRY THIS AT HOME" sign is quite funny!
