I spent 4 years at University learning that: 1) skatole and indole are the chemicals that make farts smell 2) stachiose is the substance in baked beans that make you fart - the more you cook the beans the more they will make you fart 3) only about 45% of people can fart methane 4) ruminants (especially cows) farts are the source of the majority of methane in the atmosphere. Methane is a far more potent greenhouse gas than carbon dioxide
And for years people have been blamed for killing the planet. At last, the truth comes out. It’s that old cow down the roads fault.
I remember going into Holland & Barrett's when I was working in London and asked the girl if the multivitamins would make me fart. She said " Nah mate, they'll make you fin "
Any sort of dried beef like the South African biltong. Combine it with some dried fruit afterwards and you'll make quite the cocktail of smells.
