well I've looked into using co2. but i'm trying to learn how it would work like this



but i have no idea what parts you would need or how to make it very safe. besides the obvious sprinkler valve and co2 tank...

and what if i could come up with a way to fine a way to pull back a spring like that? and where could i find a spring like that... i mean it would have to be like 3 inch in diameter or at least 2. the widest one i've seen was like a inch.

no not a standard nerf gun. those are weak. i mean a nerf rocket like this. for a projectile.

and use an over sized airsoft gun to launch it as if it were a BB.

I've been debating whether to try this option but decided to post it on here first in case I've overlooked something. would u think it would be a good idea to have a cannon (launches nerf rockets) that worked like a oversized airsoft gun. a large spring coiled up that i unleashed that would compress...
