that can reach the speed of sound
when it hits the mouth of the nozzle!
:35:05
Hey, Quentin. Sorry.
:35:11
It's called a tapered bore.
:35:14
A tapered bore. Now he's takin' off
just a little bit at a time.
:35:36
Good deed, good deed.
:35:45
I'm concerned that the mass
of the added propellant...
:35:48
compared to the mass of the empty rocket
will be too little.
:35:51
He's afraid it'll be too heavy.
:35:53
Why don't we just make it longer?
:35:55
Longer would allow increased volume
for the propellant...
:35:58
without much additional mass.
:36:00
Great idea.
:36:24
Yeah.
:36:27
We got one!
:36:53
My guess is, is we're gettin' air
pockets in the body of the propellant.
:36:57
When the fire hits 'em, they act
like little combustion chambers.
