inflatable figures are able to maintain an upright position without the necessity of external devices such as tethers . there are several ways to cause the inflatables to maintain the upright position . in one example , baffles inside the figure direct air into all areas and controls the air exhaust . in another example , the inflatable is provided with a single air exhaust at the top of the figure . as air travels from the air source , located at the base of the figure to the exhaust , the force of the air traveling through the figure keeps the figure upright . in another example , a tube receives air from the air source and is sewn to the inside of the figure . the tube bends temporarily . when the tube bends , air cannot be exhausted from the tube and the buildup of pressure causes the tube , and therefore the figure , to return to the upright position .
