Hello all,

I need to get a small electronic device (gathers weather data) into the air 1200+ ft and then have it slowly parachute down to collect data. A weather balloon won’t work because it is too slow moving as it ascends and will deviate its path based on wind/rain conditions. It can’t have a small rocket engine (no ordinates allowed) and would preferably not need a person to man it, i.e. an RC plane/helicopter would need a pilot on the ground. I am running out of options and hoped some people with more experience could offer up some suggestions. Any ideas are much appreciated! Thank you!
Edit–
Thank you all for the feedback, currently we are using compressed air, and it is indeed hooked up to a gun however this was never it’s intended use. I believe we are using 300 psi (a typical divers tank) and that won’t get it to the height we need. I can design the housing as a basic bullet to hold the payload, but I don’t think the guns components are rated to anything over what a divers tank can put out. Magnetic does sound expensive, but it is worth looking into. I also am reading up on the hyrogen pop bottle rocket. Again, thank you all for the replies, if all else failsI’ll grab some pop rocks and mountain dew!!!
