My mother always asks me not to fill the ice cube tray with water to the brim because it’ll expand and break the box. But doesn’t matter shrink in volume when heat is dissipated, so why does the ice cube expand?
Sorry in advanced, if I word it incorrectly, English is not my first language. Thank you.

Pretty sure the H-O-H bond is close to 118°. Standard molecules would be around 120. The hydrogen bonding phenomenon is what holds the angle tighter. At lower temps this bonding is “relaxed” a bit and the angle increases; therefore, becomes less dense
