4 Times Disney Got The Science Right (And 4 Times It Didn't)

5. Frozen: She's Powerful, But Not That Powerful

We all know that the Ice Queen is pretty powerful, raising an ice palace out of thin air is no mean feat after all, but it might be that Disney slightly underestimate how powerful Elsa would have to be. The thing is, in boring old physics, you can't just change the states of things without putting in work and freezing the fantasy equivalent of a medieval Norwegian kingdom would take a hell of a lot of energy. A student of integrated science called Aaron Goldberg decided he was going to figure out exactly how much energy (because that's the kind of thing science students entertain themselves with). He estimated that the amount of ice that would be needed to cover Arendelle would be about 99,043,217,000 kg. He then figured out exactly how much energy it would take for a super-efficient Carnot refrigerator to produce that amount of ice. The answer was equivalent to somewhere in the region of 115 atomic bombs. Now, even if Elsa eats all of her porridge in the morning, producing that kind of energy is like, I don't know, magic or something.
