Puff at the balloon, when it is big enough, screw the cover of head, you will find the balloon sparkling, juse like a flashing ball. It is so beautiful in the dark that you will consider to a flashing lamp. And you can hitch it on you neck, it is a big necklace, the best beautiful and largest one you have ever seen. It is also a decoration on the party, hang it on the wall, the room will turn into a colourful palace. Another good way, puff the balloon by hydrogen, look, it can fly now, be careful of the flying flashing balloon, catch the rope, don't let it go away. Maybe you will worry about that the air would go away, don't worry, the air would not go out, for there is a septa in it, the air can come in, and can not go out. Look at the balloon, there are some beatific words on it, for example, "happy birthday", "i love you". As a present, you can send it to your friends on the feast day, it can express your wishes to them, and you wishes with flashing lights. Can change the logo into your design, for example "merry christmas", "happy valentine's day", "happy halloween".
