The science of farting

**Verse 1:** Farts are funny, yes it’s true, But they have a job to do. In your tummy, gases brew, As the food is chewed by you. **Chorus:** Pop and bubble, whoosh and start, That’s the science of a fart! Pop and bubble, whoosh and start, That’s the science of a fart! **Verse 2:** As you chew and start to munch, Air gets trapped in every crunch. Down it travels, past your throat, To your stomach, it will float. **Chorus:** Pop and bubble, whoosh and start, That’s the science of a fart! Pop and bubble, whoosh and start, That’s the science of a fart! **Verse 3:** In your stomach, food is churned, Proteins, carbs, and fats are burned. Enzymes break the food apart, In this chemical work of art. **Chorus:** Pop and bubble, whoosh and start, That’s the science of a fart! Pop and bubble, whoosh and start, That’s the science of a fart! **Verse 4:** Next it moves to small intestines, Where nutrients begin their missions. Villi soak up what they find, Leaving gases left behind. **Chorus:** Pop and bubble, whoosh and start, That’s the science of a fart! Pop and bubble, whoosh and start, That’s the science of a fart! **Verse 5:** In the colon, there’s a crew, Of bacteria, small but true. They eat fibers, break them down, Making gas that’s all around. **Chorus:** Pop and bubble, whoosh and start, That’s the science of a fart! Pop and bubble, whoosh and start, That’s the science of a fart! **Verse 6:** Hydrogen, methane join the mix, Carbon dioxide, in the fix. Sulfur’s here to add a smell, Making farts you know so well. **Chorus:** Pop and bubble, whoosh and start, That’s the science of a fart! Pop and bubble, whoosh and start, That’s the science of a fart! **Verse 7:** Gas builds up, it needs to go, Through the rectum, out the show. Muscles help to push it out, With a noise, without a doubt! **Chorus:** Pop and bubble, whoosh and start, That’s the science of a fart! Pop and bubble, whoosh and start, That’s the science of a fart! **Verse 8:** Now you know how farts are made, It’s biology displayed! Chemistry and food combine, To make the gas that leaves your behind! **Chorus:** Pop and bubble, whoosh and start, That’s the science of a fart! Pop and bubble, whoosh and start, That’s the science of a fart!
