Alexis Madrigal at Wired figured that the house weighed , pounds and would require , spherical balloons three feet in diameter. Nina Rastogi from Slate calculated that if using party balloons 11 inches in diameter with 26 inches of ribbon and accounting for the weight of the balloons and ribbon, you would need over 9. Over at IMDB , someone posted that it would take 12,, balloons to lift a ,pound house. Pete Docter , co-director of Up , said that Pixar technicians estimated it would take around For the record, Pixar animators used 20, balloons in the scene where the house first took off and 10, balloons in other scenes- not nearly enough based on the variety of the above calculations.
During the married life montage movie, Carl shows off his balloon cart to Ellie. The cart starts to float away, and he jumps to bring it back down. Based on the idea that one balloon could life about 0. Finally, near the end of the movie, Russell uses a cluster of balloons with a leaf-blower to help steer to float to the airship to rescue Kevin.
Russell is six, and the average six-year-old is around 50 pounds. If one balloon could life about 0. I guess we should just assume that the helium in Pixar movies has much more lifting power than our own helium. Featured Image Credit. You are commenting using your WordPress.

That's a hard number for most people to wrap their heads around. For comparison, Cleveland, Ohio, set a record for biggest balloon release ever in , and that event featured just 1. Even that amount was enough to ground airplanes, cause traffic accidents, and send the city into general chaos.
This video uses an impressive computer simulation to show what 31 million balloons would look like in real life. The CGI balloons are shown riding the currents of the wind like a floating, rainbow sea.
That means the bottom floor is maybe square feet. This would make the side 30 feet or about 9 meters. Now I just measure the pixel size of the house and use the same pixel per meter for the spherical balloon. Here it is. The thing with party balloons is that they are not packed tightly, there is space between them. This makes it look like it takes up much more space.
Let me just use Slate's calculation of 9. How big would this look? This could be tricky if I didn't know how to cheat. How tightly packed do party balloons fit? Who knows? Pixar knows. From that Slate post, Pixar said they used 20, balloons in the lift off sequence. From that and the picture I used above and the same pixel size trick, the volume of balloons is about the same as a sphere of radius 14 meters.
This would make a volume of 12, m 3. The effective volume can't remember the technical term for this of each balloon would be:. And then this would lead to an apparent volume of the giant cluster of 9. If this were a spherical cluster, the radius would be meters.
Here is what that would look like:. You can see that there is no point stopping now. I have gone this far, why would I stop? That would be silly. The first thing to answer this question is, how long does it take to fill one balloon. I am no expert, I will estimate low. But look, the guy is filling 9. If that were the case, it would take 94 million seconds or 3 years.
Well, you can see there is a problem because that time doesn't include union bathroom breaks. Also, a standard helium balloon will only stay inflated for a few days. What if it was just 20, balloons like Pixar used in the animation? At 10 seconds a balloon, that would be 2. Remember that MythBusters episode where they filled balloons to lift a small boy? Took a while, didn't it?
