Brave Hair
Mike Seymour (via Erik Barzeski):
If you took a curly hair and weighted it and then one took straight hair and weighted it, with the same weight in mass, the way each would react to gravity is quite different.” Merida’s hair wanted to unwind due to the weight of her own hair, so the team tried lighting the mass, but then the hair became floaty “almost like underwater hair. It is not that the mass changes, it is almost as if gravity itself changes.” So the team ended up using a gravity coefficient closer to that of the moon than earth.
