In Frozen 2, a key plot point is the idea presented by everyone's favorite snowman, Olaf. He tells us that water has memory. That is a concept that has been around for a while and, while I am not one to fault the water based science of a creature that is literally made from frozen WATER, that is exactly what I am here to do. You see, that was something I needed to learn more about and, OH BOY, did I find out how bad Olaf's science really is! Don't let a snowman teach you science Theorists!
