Mis explained I suppose. I do know however due to the awesomeness that was Mr. Wizard, that the water level stays the same, my not being able to remember the exact wording from almost 20 years ago is my own fail I suppose.
Incorrect. It"s not about density, its about the space the water displaces, the amount of displacement the water has in cube form is the same it has in liquid form.
New? I saw this on Mr. Wizard back in like 1980something.
Water level stays the same due to the ice cube already displacing the area needed, so when the cube melts, the level stays the same because the same amount is still being displaced.
