Starting Up

Tomorrow is the building day so we need to know what we are doing for the rocket. This post is so we can comment back and forth on what we found was best for each part and why it is the best. During my research in class today, most sources say that a water to air ratio of 1/3 is USUALLY the best, but it depends on how pressurised the air is and the weight of the rocket. Also, we want the cone to have a bit of weight in it for stability. We need more ideas on what would be the best and suggestions for all the other parts (such as if it's a 2L, 1.5L, or 1L). I think that the 1L bottle would work the best simply because it has "the best of both worlds". It is like a dialated version of the 1L, so it is aerodynamic, but also holds more pressurised air like the 2L. We need to comment and exchange ideas.

  1. I will be buying 1.5L bottles. If you believe that the 2L bottles will work better, bring them in and we will see which design seems like it would work better.
