While I myself cannot come up with a plausible design for a bottle rocket to be launched into space I can see possible routes to take in order to achieve such a high altitude. First, rockets work on propulsion and common rocketry works in almost the same way it did thousands of years ago. Fuel has definitely changed, but the number one thing that had aided man to reach space was the development of sophisticated nozzles that channel and multiply the thrust provided by the fuel burning. The development of a nozzle for a bottle rocket could reach aid it to altitudes thought to be unreachable. The only issue I see is the back pressure developed inside the rocket due to the pressure needed for lift-off. But, added weight for structural support may not affect the flight so much. Second, Fins/Wings. There is no rule in aerodynamics that says space has to be reached at a vertical point. NASA, The Pentagon, and all other space venturing installations reach space at a vertical point because the engines they use are very powerful short term burners. The space shuttle has two solid fuel boosters attached during lift off that burn up and are dropped right before space, and has a fuel booster that it discards as well. The fuel on the space shuttle couldn't make it to space. So if the bt took off vertically then steadily "dipped" to lets say a 55 degree angle it would out less strain on the fuel source as it propelled upwards, yet there would have to be more fuel because of the longer flight. But, I work in IT not at NASA. Other people can tackle space while I tackle Microsoft... and punch it a lot.
