Up, up, and away


NINA SHEN RASTOGI of SLATE.COM asks "How many balloons would lift a house?"

Answer: a lot more than Carl used.

These figures all assume that Carl's house is simply being lifted off the ground. In the movie, however, Carl's house rips free from its foundation, which would likely require a dramatic increase in the number of balloons needed. (Consider that in a storm situation, shifting a house clean off its foundation requires wind speeds of around 190 km/h, which is what you'd find in a Category 3 hurricane.)

Plus, if the cluster were big enough to have that much lifting force, the house wouldn't leisurely float away after being unmoored, as it does in the film – it would shoot off like a rocket.

Well at least The Incredibles was scientifically accurate.
