In the last few weeks of high school my school's physics class made bottle rockets, and because I had been my own science Olympiad class I decided to make one too. The model I made was crazy simple and was literally like a missile went straight up and strait down with a lot force (bounced a good 7 feet when hit the ground). The model went according to the teacher’s calculations around 125ft all I did was took two 2L bottles and cut the top off one remove the cap and the neck of the bottle and attached it to the pressure vessel. What was key to both to get go straight up and down was the amount of weight I put in the nose of the rocket, if some wants to try this simple design it can be properly weighted to the point that it fall on its side thus giving a decent time. I may post the pictures of the rocket some time if I can ever find them. Two words of wisdom if anyone try’s the design it will take a long time to get correct but will be more consistent than any paper cone rocket that could be destroyed after any test thus having to make another cone, and fins can realy make it spin A LOT if aligned correctly thus allowing to travel strait up in the presences of wind.
I really want to find the pic’s I took of it, I named it The Predator, because the I thought it would be more fun to see my rocket come down like a missile like in Call of Duty. If a parshoot or like device are banned side gliders probably going to be what most rockets will become. I think use of plastic bottles is better than paper that is very weather dependent [rain, humidity can be catastrophic for these cones], I seen one at regionals sheer to peace’s when it was launched because it was raining and windy.
