Nope. It doesn't.
Hydrogen does not expand when cooled to temperatures that make it liquid; instead, it contracts as it transitions from a gas to a liquid state. Liquid hydrogen exists at extremely low temperatures, specifically below -253°C (-423°F) at atmospheric pressure.

One liter of crude oil contains a complex mixture of hydrocarbons, which are compounds made up of hydrogen and carbon atoms, resulting in a higher number of hydrogen atoms compared to one liter of liquid hydrogen, which consists solely of hydrogen molecules (H2). Since hydrocarbons in crude oil can have multiple hydrogen atoms per molecule, the total count of hydrogen atoms in crude oil is significantly greater.

On another related note, the fact that water expands when frozen, and thus floats in unfrozen water, is one of the many accidents of physics that was necessary for the formation of life on Earth. I can't remember why, but I'm sure we can all use an LLM for more details.

I don't get why the shaking of the tail at the end is necessary.

Wonder if that is the same kangeroo that beat up that other guy? LOL
