Re: Bottle Rocket B
Rockets either fall apart, land out of reach, or land in reach and intact. No inbetweens.

Re: Bottle Rocket B
Our secret is putting in 22.5%. I know it sounds insane, but we did some testing on our rockets. In one scenario, the rocket started leaking slightly, and launched with only about 20% water left.fishman100 wrote:I would think 60% would be too much; we were told at a competition that 50% "looked like an awful lot of water." But then we wonsquash wrote:What amount of water is the best?
I seems that nearly 30% or 60% works well.
Thanks

We got a new best time. We even shot it past the fence and into the 2 acre woods behind our school. We found it about 700 ft. away and the tip had been completely crushed, probably on impact.

Re: Bottle Rocket B
Using 22.5% water, how long did you manage to keep it in the air?
Goodbye Science Olympiad, until next year.

Re: Bottle Rocket B
Has anyone found the perfect balance of strength and lightness? I made a glider that worked perfectly, but it didn't get high enough... so it ended up not doing well.

Re: Bottle Rocket B
Not if you have the resources and knowledge to build someting very similar to or better than the ruined one.

Re: Bottle Rocket B
space scientist wrote:The most effective design this year has been the backslider which will always (if it is a working backslider) be a fairly long (or super long) bottle rocket that is as lightweight as possible with the center of balance put halfway in between the center of pressure and center of lateral area. However, there may be some adjustments to adapt the rocket to certain weather conditions.Cheesy Pie wrote:What did the 30-second rockets look like? Don't worry; I'm not going to Nats.
Edit: Never mind. I misread the question.
How do you find the center of pressure, and the "lateral area" means the lateral area of just the cone, right????????
