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.

For anyone wondering, heavy water is basically H20 but it uses hydrogen's isotope which has one neutron (instead of the regular hydrogen atom which has no neutrons) known as deuterium which doubles the mass of the hydrogen atoms making the compound 11% denser

For anyone wanting to know, you can drink heavy water, just not in large quantities without having symptoms of dizziness and low blood pressure

I like how a $100 Ice cube is melting and mixing with tap water :D

For anyone wondering, the D in D2O stands for Deuterium.
Deuterium is basically a Hydrogen atom, but with 1 neutron in its nucleus instead of 0. This makes the total weight higher (just double, actually. Weight of hydrogen is 1 amu due to just 1 proton. Weight of Deuterium is 2 amu due to 1 proton and 1 neutron) but doesn't increase volume, hence increasing the density.
These kinds of atoms where they're of the same element (same number of protons and electrons) but differ by the number of neutrons and hence differ by Atomic weight are called Isotopes.
Hydrogen has 3 Isotopes: Protium (the normal one), Deuterium (with 1 neutron), and Tritium (with 2 neutrons).

Fun fact: Heavy water is also used in Nuclear Reactor as a moderator, So chain of reactions happening can be controlled.

I love how you can see the liquid sinking as it melts.

Now put the regular Ice cube in D2O water

For anyone wondering: yes, you can drink it.
Don't drink too much and over a longer period of time tho, as it can fuck up your blood pressure.

D stands for Deuterium. Basically hydrogen atom with an added neutron. Risibly so, but denser than regular H2O. Called "heavy water", it's commonly used in nuclear reactors. Add one more neutron to Deuterium and we have Tritium, which is straight up radioactive.

I like how you can see the heavy ice cube melting and that liquid sinking to the bottom

For those wondering, the water is made using an isotope of hydrogen called Deuterium.
Atoms are made of positive heavy protons in the core of the atom, and tiny negative electrons that orbit the core. There are also neutral neutrons in the core that are a little heavier than protons. Typically for lighter elements, the number of protons, neutrons, and electrons is equal.ย
Oxygen for example most often has 8 protons, 8 electrons, and 8 neutrons, for a total weight of 16 (electrons don't really contribute to the weight). Hydrogen often doesn't have any Neutrons and is just one proton and one electron. So when you make H2O using two hydrogen atoms and an Oxygen atom, the weight of that molecule is 16+1+1 = 18.ย
Deuterium is a hydrogen atom that also has a neutron for a total weight of 2, so when you make D2O, you get 16+2+2 = 20, or about 11% heavier. Now adding neutrons doesn't really make the atom any bigger, just heavier, which is why the ice sinks.

itโs really cool that you can see it melting as well if you look closely, it looks like the two waters arenโt mixing, like gas fumes in air

you can see the slightly heavier D20 that is melting off of the heavy ice sinking to the bottom, because it is also optically denser and is refracting light, really cool.

I love how as the heavy ice cube melts u can see the heavy water sinking as well

Who else thought he was gonna violently throw the regular ice cube across the room

For those curious, D stands for Deuterium. Itโs an isotope of hydrogen thatโs around twice the mass of a usual hydrogen isotope.

It sounds like a bad joke: "How do you make a heavy ice cube? Use heavy water"
