Welcome to Science Fiction - where we take science fact...
-And blow it to flippin' smithereens.
Today's question, please, BUD E.
Just accessing me RAM chip, love. Give us a moment.
Today's question comes from Marvin in Dungarvan.
That's a good one. We'll have a craic with this.
-When you audibly pass wind...
-Yeah, or fart.
When you audibly pass wind
the vibrations in the air create a sound wave, which travels outwards.
When vibrations are low, you hear a low pitch.
-When they're fast, the pitch's high!
Sound behaves differently, depending on the material and atmosphere.
Allow me to demonstrate, and remember, do not try this at home.
Step one - eat ten cans of beans.
Step two - wait for half-an-hour.
Step three - now begin the flatulence test.
Notice how the sound changes when the professor is in open air,
underwater...and in space.
-Because space is a vacuum...
-Like almost totally empty, like.
..we can't hear the sound.
Oh, but you can still smell it. Oh, no!
So now you know, Marvin, you can't hear a fart in space.
That's just a load of old science fiction, huh?
I'm better off at a window? Whoa, what a whack! Rank!
