I am definitely not a science person, so this may be a really obvious/dumb question, but I don’t get it. My understanding was that most things expanded when heated, but sodas/beers seem to expand violently when they’re frozen. Can someone explain this like I’m five?

Water is an exception to the rule; when water freezes into ice it gets less dense (which is why ice floats in water, that wouldn’t work with say, a steel bar in a vat of liquid steel). It does this because it’s a very polar molecule, so when you take energy out by freezing it and slowing molecules down, the magnetic repulsion of individual molecules is enough to force them to spread out more than.
