Looking again, it seems that Randall is not talking about how fast the object rises, but how much time it takes to rise, hang and drift away. In other words how fast is the experience? In that case fireworks do follow the process of rising and hanging and drifting faster than a rocket does. So the experience takes less time (seconds) even though the rocket travels faster the whole process takes longer (minutes for blastoff and hours or days to return).

I think the parts of the mountain that suddenly rise(s) refers to lava, smoke, ash, etc. 162.158.122.102 07:53, 28 December 2016 (UTC)

Looks to me that Randall got the chart wrong. Rockets go much faster than fireworks. Very large fireworks can go faster than the speed of sound on the order of a couple hundred miles per hour, https://www.fireworkscrazy.co.uk/blog/how-fast-are-fireworks/ But in order for rockets to go into orbit they have to reach speed in the thousands of miles per hour, http://spaceflight.nasa.gov/shuttle/reference/basics/launch.html So the rocket ship should be to the left of the fireworks. Unless the initial acceleration of the firework is faster than the rocket. In other words for the first hundred or so feet, does the firework go faster than the rocket? Does anyone know that?
