This amazing video shows what you’d see if rockets were transparent

 A new video illustrates how four different rocket types would seem if they were transparent during lift-off and stage separation, including how the fuel drains as the rockets continue to fire.

The video color-codes a variety of rocket fuel types as they are consumed by the rockets’ various stages.

Kerosene RP-1 is a highly refined version of kerosene that resembles to jet fuel.

Liquid hydrogen (LH2), a typical rocket fuel utilised by NASA, is orange. It cools the rocket’s nozzle before being ignited by an oxidizer, which is interesting.

Blue is liquid oxygen (LOX), the liquid form of diatomic oxygen that often is used as oxidizer for the liquid hydrogen in rockets such as NASA’s workhorse RS-25, an engine that was used for the Space Shuttle. You can watch the video below:
