Airsoft Tension/Compression Mortar

I've been looking for a way to make an airsoft mortar which uses either tension (by way of wrist rocket or similar bands) or compression (by way of a spring). I'm thinking it'd be similar to the trip mine here:

https://www.instructables.com/id/Build-an-Airsoft-Trip-Mine/

If anybody could give me ideas or post an instructable, that would be great. I don't want to use air compressors or light anything on fire, because it's just not practical mid game (that would also be just a manipulation of a potato gun). I also think compression or tension could be a lot safer if done properly. Any ideas on making shells to hold airsoft bb's and properly disperse them when fired would be great too.

P.S. I'm totally willing to offer my input on the situation if somebody else wants to collaborate on such an 'ible.

well it would kind of go against your compression rule but i am currently gatthering materials to make a mortar using pvc. basically take a 1 1/2" coupling, a 1 1/2" endcap, a 1 1/2" pvc pipe, a 1 1/2" x 1/2" bushing, a 3/4" x 1/2" irrigation hose adapter, a pvc pipe to fit this inside of, an endcap to go on that pipe with a needle going through the cap inside, and a coupling nut. what you do is put the coupling, a bit of the pipe, the end cap, the bushing, and the irrigation hose thing and put it all together, this is your shell then put a schrader valve on the end cap on that shell. then take your coupling nut and put a rubber cap type thing inside. how it works is you fill the shell with water through the coupling nut, then put pressure in the shell through the schrader valve, now the compressed air will push the water out and push the shell out of the tube or barrel... basically im modeling it after this http://www.youtube.com/watch?v=fYggp2moVWQ&feature=related and the reason this COULD work with pressure is you could make several of these shells and fill them before the game, then use those like that. if you need any diagrams or anything just ask ill put em up for you

Thanks. To be honest, I'd completely forgotten about this post. I'm glad it sparked some interest though. Best of luck with constructing your mortar.
