Slush hydrogen
Slush hydrogen is like really, really cold ice cream but instead of being made of milk and sugar, it's made of hydrogen gas. Hydrogen gas is the lightest and most abundant element in the universe.
When hydrogen gas is cooled down to -423 degrees Fahrenheit, it becomes a solid! This is cold enough to make all of the tiny atoms in the gas slow down and stick together. The result is a weird, gooey substance that's not quite a solid and not quite a liquid - it's called "slush".
This slush can be used as a fuel for rockets because it takes up less space than normal liquid hydrogen, and it can be pumped into the rocket's tanks more easily. Plus, since hydrogen is a really clean burning fuel, it's better for the environment than other types of rocket fuel.
So, slush hydrogen is a super cold substance that can be used as a cleaner and more efficient fuel in rockets.
