Rocket Camp Keeps You Busy

I feel guilty for not blogging much recently. Between teaching rocket camp, my day job, and preparing to move to Boston a week from Tuesday, I don't have much free time.

But camp has been going well. Several parents have told me that their kids have learned a lot. Which is great - and sort of surprising. These kids have absorbed a lot of technical information. Sometimes I've mentioned something once on one day, and half the kids don't look like they're even listening, and two days later, I'll ask a question, thinking I'll need to re-teach the information - but the kids know it! Concepts like total impulse and center of pressure are not easy to grasp at first, but these are some smart kids.

Anyway, rather than writing up each week in separate posts, I'll take what I've learned about teaching rocketry when I'm all done, after Friday. While this blog is partly for people who are n00bs to rocketry, maybe there are a few more experienced rocketeers who are n00bs to teaching rocketry, and maybe my experience will help you prepare.

In any case, I was able to get a little painting done. Ivy Tech has a really nice spray painting booth, and I was able to get Keith's Rocket painted. I'm pretty proud of it.

I'd originally bought the copper paint for the fins on the 3D Rocketry Nautilus II, but that rocket was lost before it was finished. Still, it looks great! I'm going to have to build one of these for myself.

The rocket has a payload compartment. Four small holes - known as static ports - allow you to fly with a barometric altimeter, such as the Jolly Logic. An altimeter needs to breathe to function, so you put static ports in your rocket to allow the payload compartment to equalize in pressure with the air outside the rocket.

I have four more Donor's Rockets to finish painting. I hope to launch these next week - after rocket school!
