How high a balloon rises depends on what kind of balloon it is. A small helium balloon that you get at a party will go up about 10 kilometres (6 miles). A giant balloon carrying a person may rise 32 kilometres (20 miles) or even more. Scientists also send up balloons with instruments that study the Earth. These balloons often travel about 40 kilometres (25 miles).
