Space Shuttle Main Engine

Space Shuttle Main Engine

Take the tap off that liquid hydrogen that's being pumped around to the engine, the red hoses duct it down the side of the nozzle, through these distribution tubes.

This is where the big fireball come out the backside.

It's going to fill up these manifold and then it's going to flow back up through 1080 tubes into the
main combustion engine and burn it.  The actual fuel sent along these pipes. These tubes cool it down protect the nozzle from the heat of the engine. And then the fuel goes in and burn.

This is a chocolate ice cream kettle inspired by NASA. This challenge is to stop my ice cream from melting as the water heats up.

Use the liquid propane fuel for the burner. Just like the space shuttle using the freezing-cold fuel
to do the cooling.

As you can see vapor come from the boiling water and ice cream is still frozen. 100 degrees on the inside, below zero degree on the outside.
