“‘Getting it right’ is not opposed to good storytelling.” Carroll says.

Maybe the warmth of Anna’s heart, he said, could melt her sister’s spell. The filmmakers liked the idea, and thus an iconic scene became both emotionally and thermodynamically appropriate.Īnyone who hopes Hollywood will educate the world about science is signing up for disappointment: The Science and Entertainment Exchange, a National Academies of Sciences project that connects filmmakers with volunteer scientific advisers, gently warns prospective advisers that “sometimes the story or production needs of TV and film conflict with strict scientific accuracy.” That’s an epic understatement. But Sean Carroll, a physicist who has advised Thor, The Avengers, and other movies, points out that collaborations between science and Hollywood can head off stereotypical portrayals of scientists in movies, help keep audience belief enjoyably suspended, and even inspire cool new storylines, from frost fairies to time travel. Should she melt in the sun, the filmmakers asked? How about a warm breath of air? Well, said Painter, the fastest way to melt ice is to put it in contact with something warm and solid. The creators of Frozen went to great lengths to make their animated ice and snow believable, consulting with avalanche forecasters, hydrologists, and most extensively with Caltech snowflake expert Ken Libbrecht. (The special-effects team also went to Wyoming, where they spent some time walking through deep snow in long, princess-y skirts.) Painter was asked for advice on the movie’s climax, where Anna, whose frosty sister has accidentally trapped her in a block of Anna-shaped ice, melts her way to freedom and a happy ending. Well, just kidding about that last part.ĭisney called on Painter’s expertise again a few years ago, when the company was developing Frozen, a little flick you may have heard of. Tinkerbell and Periwinkle are reunited, the King and Queen of Fairy Hollow acknowledge their long-denied affections, and all the fairies give thanks to the laws of physics. “It acts like a little- blanket.” The frost fairies work their insulating magic on the home tree, the storm passes over, and everyone-including the tree-survives.

In the final version of the film, as the fairies watch the storm advance toward the Home Tree, one suggests that they cover the tree with frost to protect it. What about sending a frost fairy to the rescue, Painter asked? Frost fairies could be very, very useful. Frost and snow, which trap warmer air in the spaces between ice crystals, would be far better insulators. Given the ferocity of the cheese-grater-inspired snowstorm, the air outside the Home Tree would be much colder than the tree itself, and a thin layer of ice would just pull heat out of the tree more quickly. That’d work, wouldn’t it? Painter traveled to California to meet with the filmmakers, and he gave them a PowerPoint presentation whose title he remembers as “Thermodynamics, or Why You’re Going to Kill the Fairies.” The water-on-grapes trick helps the fruit retain heat, he explained, only when there’s a relatively small temperature difference between the inside of the grape and the air outside.

One of the Tinkerbell screenwriters, who happened to live in wine country, suggested that the fairies sprinkle the tree with water, sort of like grape-growers do before a freeze. What’s a brave pair of seasonally mismatched sister-fairies to do? The storm spells big trouble for the Home Tree and its all-important fairy pollen, neither of which are, shall we say, cold-tolerant. The snowmaking machine goes haywire and somehow creates a snowstorm all over Pixie Hollow (I didn’t catch the cause and effect there, but it made perfect sense to my five-year-old). Problem is, Tinkerbell can’t survive in the Winter Woods without a coat, which interferes with flying, and Periwinkle can’t survive outside them without a snowmaking machine that Tinkerbell and her friends fashion out of a cheese grater and a lump of ice. Painter started his fairy-princess sideline a few years ago, when he was asked to lend his expertise to Tinkerbell: Secret of the Wings. In the movie-bear with me here, okay?-Tinkerbell makes a forbidden crossing into the Winter Woods, where she meets her long-lost twin sister Periwinkle, a Frost Fairy. He’s also a leading expert on the thermodynamics of fairies and princesses. Tom Painter, a research scientist at NASA’s Jet Propulsion Laboratory in Pasadena, studies snow hydrology in mountains around the world.
