I was wondering if designing an ETG-type Film-can cannon would be at all reasonable. Use some Camera Flash circuitry with a few extra caps to vaporize a piece of aluminum foil, with the shockwave propelling away the film can.
Would this even be possible? What would be potential problems?

I actually tried making a simple one from a Epoxy Putty plastic tube as chamber, and pen tube as barrel. When fired, the Chamber blew up. You might be fine though, film canister is a bit thicker, more flexible, and i used ~800j :D.
Its really easy to make one out of PVC, and even metal. Mine is small metal union as chamber, plenty big. Look on website, Electrothermal Guns-ETG2. Website is in my sig.

Ive had PVC shatter, but it was when i put alot of water in it, so the pressure was forced to explode it (this was with 640PSI rated PVC!) I say stick with metal, i even used 1/2" copper pipe well.
