The string is threaded through the straw and is attached at both ends to fixed objects. The straw is then taped to the side of the inflated balloon, with the mouth of the balloon touching the object it is pointed. When the balloon is released, it propels itself along the length of the string. Alternatively, a balloon rocket car can be built. A rocket balloon without its pump attached. There is also dedicated toy known as a rocket balloon, usually tubular-shaped and inflated with a special pump (pictured). These balloons, when released, propel in a more stable direction because of a steadier thrust of air and elongated shape, unlike ordinary round balloons which often launch uncontrollably. Aside from the shape, rocket balloons are also characterized by their distinctive loud buzzing or screaming noises due to the tight, reed-like opening designed to make noise as the air rushes through. They are also known as noisemaker balloons, due to the aforementioned noise….’ ].
