Explaining the Delta Rocket Fireball

YouTube description:

Every time a Delta IV launches people inevitably ask if the rocket consuming fireball is supposed to happen. The answer is yes, this is caused by the rocket purging its engines with hydrogen before letting the hydrogen/oxygen mixture into the combustion chamber. But there's more to it that that of course.
