Think it was a high school physics demonstration where a glass bottle is filled to the brim with water and then dropped to show it doesn't break? Something like that, or you can hit it fairly hard with a hammer and it won't break as easily compared to an empty bottle.

That and boiling water in a paper cup over a bunsen burner (chemistry class) are some of my favorite science demonstrations!

Was literally talking to someone the other day about water being irregular in how it expands at freezing temperatures opposed to contracting.

Water/H2O is such a cool molecule/substance

Every science including physics consists of models that are just good enough for a particular use case. It's implied
