A learning day at the Jer Zone.
- Kirk is right: shave most of the nose cone down, it doesn't stick, and the water rocket parachute deploys.
- Surface wind, or lack thereof, is not an indicator of winds aloft.
- Parachutes and trees are the magnetic north and south poles of rocketry: highly attracted to each other.
- Winds aloft only make this attraction worse.
- Unrelated, but hey, I ran out of rockets to shoot: the little red worms in the pond filter aren't a bad thing.

Dude! Your rockets rock so much!
What I want to know is how do you get that real rocket sound? All the bottles I send up just go "PAP - Ffffffttttt" not "BOW- fffoooWhap!" like yours.
I had no idea the rocket sounded so good until putting the camera/mic inside. The mic is inside the top bottle so it must be hearing some of the water exiting (a fraction of a second) and the rest is wind rushing past?
I've almost got my video rocket back together for another shot. This time using a two liter engine and a *new* and *improved* parachute system. If all goes as planned I'm hoping for a really high altitude shot with a long, slow descent.
Given that the last parachute system is still hanging out in a tree top we're going to have to come up with a better launch site.
