I do a summary of our family's rocket activities every year*, and this year y'all have the chance to look it over if you'd like. *yawn* It's in the extended entry.

*We've kept complete records of every flight we've ever made. It's a good way to gauge our progress as we advance in this hobby, and helps us to figure out what happened when things go wrong. more...

If you remember the old rocket companies of our youth, you might want to check out these shirts with the classic Centuri logo.

Or these cool SciFi designs.

Hmmm... "Space Cadet" or "It's the Law"... "Mad Genius" or Still Life. Too many good choices.

He's got some very nice celtic designs too.

Here's a simple and inexpensive way to get a fair estimate. There are three diagrams, so expand the extended entry to read the surprisingly easy method we use.

1 Mark I Eyeball only has three measurements, tho: High, Really High, and Hey, God! Little help?

Heh. OK, that's my lame attempt at rocket humour. And I haven't even taken any cold medicine!

2 Dang, I thought I invented that device!
After your post about Air Munuvia's maiden voyage I wondered how you could determine how high it went. "Easy," I thought, "just measure the vertical side of the right triangle by looking along it's hypontenuse from a known length of the horizontal side!" (I never got around to writing up a table, though.)
This is as disappointing as the time when I was in K-mart, aged 9, and discovered that my battery-heated socks idea had already been invented.

3 Also, that system is accurate only if the rocket climbs perfectly vertically. It would be a good idea (if you really want an accurate measurement in the case of a competition, say) to have someone else with a perpendicular view to measure the angle from the launchpad to the rocket at apogee.
If the rocket curves toward the tracker then the reading with show that the rocket had reached higher altitude than it actually reached; and it curves away from the tracker then the reading would understate the true altitude.

5 D'oh! I guess I stopped reading too soon.

6 Easiest way to tell how high a rocket went is to launch it indoors.

WhooshCRUNCH!

"About eight foot six, wouldn't you say?"
