Professor Amadeus told me that he filled a 2L bottle with water, probley half way and then stuck it on his barrel (of his spudgun) and fired it off. I think it will have the same effect as a normal lock down water rocket. You will need a lot of air though. Just lube the barrel on the outside and fix an o-ring to the bottle lip.

We made one in Aerospace Engineering for a project and it went 70 meters high. We did all the maths and calculations on it. I could put the report on this forum. It tells u the optimum fins, center of pressure, center of gravity and even thrust calculations. How can I post a document on this post?
