Ice normally floats on water because as water freezes it expands, and the density of the solid becomes less than the liquid. This on the other hand is an ice cube that I made, but this one's kind of special, and it's able to sink.
This is because it isn't normal water, and it's actually heavy water. This heavy water (D2O), is made when the hydrogen of regular water (H2O) is replaced with deuterium, which is a heavier isotope of hydrogen. Heavy water is about 11% denser than regular water (H20), and this extra weight lets it sink.
