Tyler, Im thirteen! This is a science project; i can use a film canister if I want! This isn't actually a submarine model!
Other Guy, I can't 'contaminate' the water; I can only use Alka-Seltzer!

While I have never build a model subarine, I have constructed several 1;96 scale model surface ships, including the USS Abbot (DD-629) and the USS Gambier Bay (CVE-73).
However, several members of my club have constructed fully functioning model submarines and are both members of Task Force 100, the club in which I am a member, and a model sub club known as the subcommittee.
The guys in this club should be more then willing to assist you with your problem and I have included the link to their site below.
I hope that this helps.
