It was about an old man who used thousands of ballons to lift house up into the sky and fly to sout America.
It was a fun and interesting movie,but it's not a new idea.
Over the years, several people have tried to build their own homemade aircrafts using balloons.
An American man from Oregon named Kent couch tried it in 2001. He tied 105 large balloons to a big chair.
Then he filled the balloons with helium,a gas that is lighter than air. To keep his chair from flying up too high,he had bags filled with water attached to the chair.
These bags acted as weights.
If he wantedbto go up,he just let some water out of the bags.
