How Will Balloons Look That Lift Your House Up?

There's an interesting article about Disney-Pixar's new movie Up.
How Many Balloons Will Lift Your House Up?

It says,
According to Pixar, Carl's house in the film attains liftoff with about 20,000 balloons. But for the sake of realism, director Pete Docter and his crew wanted to know how many balloons it would take in real life to make the scenario plausible, which came in at 20 million to 30 million.

I just wondered "what if there are 20 million balloons?", and tested it.
Each balloon is r=10cm sphere and the house is 15m x 7.5m x 7.5m.

Hmmm, I guess just 20000 balloons might possibly look better...
