Now, I was thinking this was just a matter of shaking up a coke bottle real hard and letting the escaping CO2 power its flight. I trust from your comment that I'm missing something. Likely since I watched the video without sound. LOL

Aha! I sort of recall doing that once at the urging of one of the kids. Don't recall which one, but we never got the bottle to fly. A failed experiment that needs to be repeated because of failure to follow instructions well. lol
