After watching the film “Up” many people wondered how many ballons would it take to lift a house or how many balloons did Carl tie so that lift his house and travel to South America?
Pete Docter, Up co-director, said that technicians at Pixar estimated it would take 23.5 million party balloons to lift a 1,800-square-foot house like Carl’s, though it’s unclear exactly what size balloon they were using to make their calculations.
Got anything to add?
