One Boy One Cup
Back when I was small I'd stumbled on to realisation that your own farts smell pretty good. Further thought and I'd noted that by the time they reach your nose they'd been pretty diluted. Just imagine if you could capture the fart whole! How amazing would that smell? In the bath that night I got a cup, filled it with water and strategically positioned it upside down. Burbling came from below and success! Carefully I moved my nose to the water's edge, lifted the cup and inhaled good and proper.

...And nearly vomited on the spot. Your own farts smell reasonable BECAUSE they've been diluted. Don't go to the source.

Ah, but you haven't done a fair test.
For some reason (I know not the science), farts which bubble through water tend to smell worse than they otherwise would.

So, it might not be that you concentrated it that made it terrible... it might be some chemical transition that occurred before it even reached your nose.

Short answer... underwater farts have more carboxylic acids in them.

Longer answer...
...when your fart breaks the surface it is still at full concentration and it's half the usual distance from your nose.

Did I really spend time thinking that through? FFS!

So
Farting is safer in shallower waters

Awesome
Science has clearly moved on since my boyhood.

THIS IS PROPER SCIENTIFIC RESEARCH
