Great question. I'm new to the forum and just realized I posted this where it probably shouldn't be.

The purpose is practical, surprisingly so. I can't risk divulging any further specific information as to the actual application or risk giving away what I believe to be an extraordinary lucrative idea. Not without legal agreements in place. Surprisingly enough given the life jacket idea, it does relate to life safety, and I've actually explored compressed gas, but the potential energy stored may create too significant of a hazard. If any knows a chemist or chemical engineer who does freelance work that is ultimately what I'm looking for with this post.

It's almost that simple. Picture a self inflating balloon made of cellophane. I have a chemistry question regarding some very basic principles. The materials involved: cellophane, acetic acid (6% vinegar), and sodium bicarbonate. The goal: For a 6 liter cellophane sack (balloon) to be filled using the CO2 produced from the reaction of acetic acid with sodium bicarbonate. The entire process must contained within the cellophane sack. Diluted acetic acid stored in an internal bladder within the cellophane sack is physically ruptured to expose it to the sodium bicarbonate, also contained with the sack. The entire process must be relatively safe... such as only minor skin irritation if contacted. Is there a different combination of chemicals I should be looking into? Any other considerations? This set-up will be exposed to outdoor temperature extremes from Arizona to Minnesota. Any input is appreciated! I'm currently looking for a chemist to get involved with the bigger project this question is a part of if there is any interest in discussing this further.
