Uhh i just went and a rubiks brand to play with as i wait for my edison cube. for some reason its make a definitite scratchy, and very very springy sound. also, when i shake it, i hear something bouncing around. im not sure whats wrong. either i need to break it in more, or something fell or something like that. so ill just ask two questions. whats a great way to break in new store bought rubik's brand cubes? and, how do i correctly pop open my cube. please dont give me anything that will break my cube. its brand new and very very tight so i dont see how. hope you can help. thanks!
