What were key design elements of the winning one?

A cone, it seemed

More details, please. And a cone as what?

Winning time was around 28 most of the top ten where between 21-25 seconds. There were tons of 18-19 second rockets.

I think 3rd-10th place was all 22 second rockets, if memory serves.

We got 14th with a ~20 second rocket (maybe a few hundredths less or more).

3rd- 10th was not near 22s. We were 3rd with 26. I think 6 was around 24s.

Sorry for the double post, but you need to stop asking this. You've asked this 4 or 5 times. You'll probably see some of the top rockets in the best of 2011 photo gallery sometime soon. All the top rockets pretty much looked the same. Either a long cone or a long tube for the nose. Their fins were tilted or the bottoms of the fins were angled for the rocket to spin upon takeoff. They were all built of the lightest materials possible for max height.

Ah okay. I remember reading the "unofficial leaderboard" right after we went, so that may have not been updated...

Sorry. I am WAY too lazy to check the Gallery. Lol.

They have used one liter bottles before because i remember they are a pain to find so i hope they stick with two liters

My family doesn't drink nuch soda, so we generally waste the soda. Lol.

!!! Then you could give it to me! lol

We usually don't drink soda either; the most we've had (and probably will ever have) is during the bottle rocket construction, where we needed to empty out the bottles. Aw man, I wish I had that bottle of Mountain Dew again
