7 up

After seein' several small rockets fly out o' sight, me hearties, I wanted a rocket that would spend more time where I could see it. Blimey! Ya scallywag! I wanted somethin' large, shiver me timbers, so it would be highly visible, arrr, arrr, but with low enough power for a slow, me bucko, majestic lift-off. Avast! Body tubes and nose cones get expensive rather smartly when you go beyond a BT-80, shiver me timbers, so I looked for a cheaper alternative. Avast! I thought o' usin' a 2- liter pop bottle for a body tube, shiver me timbers, and realized it would also make a neat boat-tail. Ya scallywag! I be lucky enough t' have a friend who found an old 2- liter in his basement with a rounded bottom-- t' kind that sat in a plastic cup for stability. Begad! This allowed me t' give me rocket a rounded, me hearties, ya bilge rat, torpedo-like nose. Begad!

T' newer style bottles with 5-lobed bottoms will work, me bucko, arrr, too, you'll just have an alien-lookin' 5-lobed nose cone. Arrr!
