Underwater Diving Bell
If someone dunks a diving bell underwater and farts it up enough to surface, would the air be breathable?
The diving bell would be dunked without air prior to farting it up, therefore the entire pocket would be pure fart. It would take more than a few people though to fart it up enough to surface, assuming of course, it could be done.
Who would be crazy enough to get in it and take a breath?
