Hi all, I am hoping to make a model Space Shuttle, and need help with what to use for propellants I have always been interested in space, and aim to become an Astronaut. I wish to study rocket science and aerodynamics, and making this would help me Currently, this is all theory, and has been put on paper, but I am here to ask what I should use for propellant. I am only hoping for it to go a max of 10m high, and am currently planning on using 5 cans. Does anyone have a suggestion on what I could use that is easy to obtain and has a lower risk of exploding? Thanks
