      In space, there is no pressure. There are no air molecules in space to push anything. So if you try to blow a bubble in space nothing will happen. The air molecules inside the bubble have nothing to push against so the bubble will pop before it starts to form. The bubble can only exist when there is equal pressure inside and out.
