Q:
Hi,
I had a bottle filled with water that was submerged in ice but taken out before any ice formed inside the bottle. I then placed the bottle in a bowl filled with warm water. How come the water level decreases slightly but only for a second and then rises again?

A:
It turns out that near 0°C, water contracts as it warms up. Above about 4°C it expands as it warms up. So what you saw makes complete sense.
Here's a picture, from :
Notice that's the density, inversely propotional to the volume.
