Floating Balloon Description: This product can float in the air, but all balloons filled with air cannot float. Only when filled with hydrogen or helium can the balloon float. Due to the explosive nature of hydrogen being unsafe, we do not recommend its use. Our store's pumps are all air pumps. If you need to float, you can purchase helium elsewhere. Our store only sells balloons, not gas. This link includes balloons but not strings
