Good news! I have been seeing whether or not I will be able to make a model Saturn Rocket for the challenge. I did bottle rockets way back in 2006, but all the stuff, Including the ubertastic launcher, is gone now. Good news is, I have found a way to splice bottles, and tested it today. Works pretty good so far, and I will be making a full scale test rocket soon. I don't have my launcher that was super awesome, but I do have a small Clark Cable launcher, hand held version. I do plan for my Saturn Rocket to not only have an Instructable, but an Instructable detailing splicing bottles, adding a parachute system, and adding a small package (in my case, the small lunar ship). If all goes well... I should finish before The end of the contest.
