That reminds me of when I was a kid, farting in the bath. As I saw the bubbles coming up to the surface, I wanted to catch them.

So I took whatever plastic container I could find around the bath - most likely the cap of a shampoo bottle - submerged it, and held it close to my butt when I felt the next fart coming.

I succeeded in catching some of the fart in the cap. Then I claimed my prize by sniffing directly from the cap. It was so much worse than any fart I've ever smelled.

As a true scientist, I've repeated the experiment on a few later occasions, and without a doubt : bath farts captured in plastic containers smell much worse than normal farts.

Thank you for coming to my TED talk.
