Chase chose rocketry as his 6th grade science project. It's been a hoot.
Airburst Mighty Missile, Digital Min/Max pressure gauge, Air Burst Rocket
Launcher (w FedEx ground still), polluted air, a bike pump, a shock pump,
a 12v tire pump, hours online, etc.

Hypothesis:
IF you increase Pressure or Volume
THEN the rocket's initial velocity and final height will increase
BECAUSE the PV product represents the energy lifting the rocket.

(The converse, inverse, and contrapositive are TRUE also.)


Vertical Motion Eqn:
h(t) = -16*t^2 + v0*t + h(0)
where
h(t) = height of rocket at time t
v0 = initial (and final) rocket velocity
h(0) = height of rocket at time t=0

v0 = 16*time_of_flight

(QuickTime can/did split the HD video clips into individual JPGs,
one per frame, showing the rockets in flight.)
