Based on the principle that hot air rises, the balloon works when the burner fuelled by propane gas is positioned under an open balloon envelope to heat the air and make the balloon rise. When the parachute valve at the top of the envelope is opened some of the hot air escapes, and the balloon sinks and the hot air won’t escape from the hole at the bottom of the envelope because buoyancy keeps it moving up.
