Watch: People actually make videos that explain everything you need to know about flatulence
Can you outrun them? Are the silent ones smellier? Do we like the smell of our own hot air? These Canadians know all.
AsapScience is a YouTube channel by Canadians Mitchell Moffit and Gregory Brown that aims to make science fun.
In the video above, since, as the narrator explains, "there is nothing quite like...the painful inevitability of it crossing your nose's path", the duo wonder whether it would be possible to outrun one. Now, even the fastest human – Usain Bolt, who runs at a speed of 12.4 metres a second, can't outrun the sound of one, which travels at roughly 340 metres a second.
Why, not even a Peregrine falcon, which travels at 82 metres per second, can outrun the sound of its own flatulence. So average humans are advised not to bother trying.
Could we outrun the smell – that's the part that matters anyway – of one? Here's a way to make them more palatable. They "are like snowflakes, each with its own variant. And only one per cent is made up of the smelly stuff." And since multiple factors affect the movement of the gas: room temperature, wind speed etc, there might be a chance that you will be able to outrun your flatulence. A very very slight chance.
There's also a video about the burning age old question. Are the silent ones smellier than the loud ones? The short answer? Yes, they are. Watch the video below for the longer smellier answer.
In Freedom, American novelist Jonathan Franzen wrote, "Although he, like all people, secretly enjoyed the smell of his own farts, the smell of his shit was something else. It was so bad as to seem evil in a moral way.”
The video below seeks to answer that question, "Why do we like our own farts?" Every single day, humans commit 70 billion acts of flatulence. Or, around 10 per person. Sorry, but it's true.
