Hey Group, http://hometown.aol.com/txsnapper/everclear.html Here is my new rocket made from the tall skinny one liter bottles I found in England. I have not...

... Looks pretty capable. But with so much focus on aerodynamic drag reduction, why are you still using *HD*TT instead of something else? I mean you have all...
Dumb question but this has been nagging at me. If you use an altimeter that measures altitude by air pressure, I would think that the Bernoulli effect (an...
The altimeter question ... or how to make sure an Altimerter 'tells the truth' has long been a concern of mine too. I'd sure like to know more about this. ...

Hey Mike, ... No such thing. ... think that the Bernoulli effect (an increase in the velocity of fluid flow will result in a decrease in the static pressure)...
I just got back from getting a couple of launches before it got totally dark. EVERCLEAR performed very well. I didn't have time to get really set up so I just...

Hey Steve, ... fin-based stability? Get the CP/CG right and you do not need fins at all, right?<< The CP/CG is very well placed (altimeter and battery in the...
Hey Group, It would be fun to have an altitude record established for people to shoot at with a regular soda bottle containing only water and air. I know a...
Robert, Does the rocket need to have a recovery system? If not, bounce recovery will simplify things, and give us water rocket novices something attainable to ...
More "fun" would be to have a way to report personal bests based on configurations and basic stats (like the numbers that Clifford captures in his sim or a...

i like the idea of SIMPLE RULES - recovery systems optional etc. the two classes proposed, UNLIMITED and UNMODIFIED (Single Bottle), both using only air, water...
