When Rosie Reveres Uncle Ned gets carried away wearing his famous helium pants, its up to Ada and friends to chase him down. As Uncle Ned floats farther and farther away, Ada starts asking lots of questions: How high can a balloon float? Is it possible for Uncle Ned to float into outer space? And whats the best plan for getting him down?
