Why Does Water Make a Fart Smell Worse? The Science Behind Stinky Swimming Farts

Hey friend! Have you ever noticed that farting in the shower or pool makes the smell WAY worse? As an expert in home renovation and plumbing, I‘ve learned all about the science behind gassy smells traveling through pipes. And it turns out, there‘s a good reason why water makes farts reek even more!

In this detailed guide, we‘ll dive into:

• How farts develop their signature stink
• Why water makes fart smells more intense
• The acoustic volatility of underwater gas bubbles
• How temperature, chlorine and humidity impact fart smells
• Just how common (and rude) it is to fart while swimming
• Whether sharks and other animals fart underwater
• Tips to reduce pool and tub flatulence
• When to see a doctor about stinky gas

Grab your nose plugs, this is going to get smelly!

Where Does Fart Smell Come From?

Before we get into why water makes it worse, let‘s look at how farts get smelly in the first place.

Farts contain a mix of the following odorless gases produced in your gut:

• Nitrogen: Up to 86%
• Hydrogen: Up to 10%
• Carbon dioxide: Up to 10%
• Oxygen: Up to 3%
• Methane: Around 1%

The signature rotten egg stench of farts comes from trace amounts of sulfur-containing compounds like:

• Hydrogen sulfide: The main culprit, makes up less than 1% of fart content
• Methanethiol: AKA methyl mercaptan, also produces a rotten smell
• Dimethyl sulfide: Found in cabbage farts

Where do these smelly sulfur compounds come from? They are byproducts of protein breakdown by your gut bacteria. They can also form when sulfur-containing foods interact with digestive enzymes.

The worst fart foods for producing sulfur gas include:

• Eggs
• Meat
• Milk
• Broccoli
• Cauliflower
• Brussels sprouts
• Beans

When intestinal gas heads south into the rectum, these stinky molecules hitch a ride. Once expelled from your bottom, the fart gases diffuse into the air, carrying the smelly sulfur compounds with them.

Now let‘s look at why this process makes farts smell even WORSE in water!

Gases Behave Differently Underwater

Here‘s the deal: gases have varying solubility in water. When a poot bubble forms underwater, the different fart gases will act in distinct ways:

• Oxygen and nitrogen: These have LOW solubility. They rush to the surface in bubbles and burst into the air.

• Carbon dioxide: Has MEDIUM solubility. Some bubbles up, some dissolves.

• Methane and hydrogen sulfide: Have HIGH solubility. They stay dissolved in the water rather than reaching the surface.

This difference in solubility has two stinky implications:

1. Odor Molecules Spread Further

Because stinky hydrogen sulfide and methanethiol readily dissolve, they don‘t group into discrete bubbles that then pop at the surface. Instead, they diffuse through the water, spreading the fart smell far and wide!

Dissolved fart molecules have more surface area contact with your nose and eyes underwater. You‘re immersed in a cloud of butt stank!

2. Bursting Bubbles Release Extra Smells

The gas bubbles that DO make it to the surface will burst, momentarily shooting their contents into the air. This adds an extra puff of hydrogen sulfide and mercaptan molecules to the fart atmosphere.

Essentially, farts produce a 1-2 punch of extra stinky underwater. Blech!

Additionally, warm water can increase diffusion and intensity of the smelly molecules. Let‘s look closer at temperature effects next.

Hot Tubs, Baths, and Pools Magnify the Reek

Did you know warm water temperatures allow more dissolution and diffusion of stinky fart gases?

That‘s right – hot tubs, baths and heated pools are prime environments for enhancing underwater fart smells. Here‘s why:

• Warm water opens pores on gas molecule surfaces, allowing more diffusion and dissolution.

• Heat also expands the gas, helping it spread out further in the water and air.

• Bubbles in hot tubs actively churn and burst, shooting extra farts smells into the air. It‘s like a jacuzzi turbocharges the whiff!

• Steam and humidity in baths and hot tubs trap odors, helping them linger longer.

In fact, a 2011 survey found that 27% of people admit to farting in pools on purpose, with 81% saying they witnessed such an act. Just remember – an underwater poot in a hot tub can backfire and turbulence can hit you right back in the face!

Now, what about chlorine? Does it help combat the stank underwater? Let‘s explore.

Chlorine Doesn‘t Always Neutralize Fart Smells

Many people think the chlorine in pools magically erases all fart smells. Unfortunately, that‘s not quite the case!

Here‘s the deal:

• Dilute chlorine alone can‘t fully combat potent sulfur-rich fart compounds.

• In fact, mixing chlorine with certain sulfur gases can make them MORE volatile!

• A highly chlorinated pool might mask mild fart whiffs. But concentrated flatulence can still overpower chlorine.

• Fart chemicals may also react with chloramines in the water, making additional stinky compounds!

So while chlorine helps, it‘s not a 100% underwater fart solution. A serious case of the trots could still penetrate the pool party atmosphere, so be warned!

Okay, so now that we‘ve explored the science behind it – just how common IS farting while swimming?

Farting in The Pool – Common But Rude!

Given the stink magnification, intentionally passing gas underwater is considered poor pool etiquette. However, it‘s also pretty darn common!

• Up to 27% of people admit doing it on purpose in pools and hot tubs.

• 81% of people report witnessing someone fart while swimming.

Accidental bottom burps underwater are also frequent, thanks to breathing patterns and swallowing excess air. But remember, an underwater poot can backfire, so fart at your own risk!

While farts can‘t always be avoided, it‘s good form to move away or step out of the pool if you feel one brewing down below. Most folks will politely ignore it, but the smell does dissipate quickly once you move!

Do Sharks and Other Animals Fart Underwater?

You might be wondering – wait, what about sharks and other marine creatures? Do THEY cut the cheese in the deep blue sea?

Well, here‘s what we know:

• Very little research exists on sharks specifically farting. But like other fish, it‘s presumed they expel gas from their rear cloaca openings.

• Scientists better understand whale and seal farts. They definitely do poot, contributing to oceanic methane emissions.

• Underwater, these marine farts likely dissolve and disperse stinky molecules similarly to human farts.

• However, underwater fart etiquette is presumably looser out there in the animal kingdom!

So what can another gaseous mammal do to avoid the dreaded underwater toot?

5 Tips to Reduce Pool and Tub Flatulence

While farts can‘t always be prevented, here are some friendly tips to minimize the chance of one slipping out during your next swim:

1. Move away from others – This reduces the spread of odor molecules and noise pollution from your bottom burp.

2. Cup a hand over your behind – This can muffle the sound and contain extra bubbles from a submarine poot.

3. Stand up or change position – Releasing gas into the air is your fastest ticket to reducing the stank.

4. Take a bathroom break – Heading to the toilet before swimming can let that stubborn fart out in privacy.

5. Avoid carbonated drinks beforehand – Bubbly beverages increase swallowed air and gas buildup on board!

Bear in mind, most fellow swimmers will politely ignore the slip up. Just act natural and continue having fun in the water!

When to Talk to Your Doctor About Smelly Gas

If loud, smelly flatulence becomes an ongoing problem in or out of the pool, it‘s worth making a doctors appointment.

Excessive stinky gas can indicate underlying conditions like:

• Food intolerances
• Irritable bowel syndrome (IBS)
• Small intestinal bacterial overgrowth (SIBO)
• Gastroesophageal reflux disease (GERD)
• Celiac disease
• Gallbladder issues

Your doctor can help identify causes of excessive farting and provide treatment suggestions. This may include dietary changes, probiotics, antibiotics, or gastrointestinal medications aimed at reducing intestinal gas.

So don‘t let recurring smelly gas cramp your pool party style! Seek medical guidance to get back to fart-free swimming happily.

The Bottom Line (Of The Pool)

Letting loose an underwater poot is basically inevitable if you spend enough time in pools, tubs, lakes, and oceans. When gas bubbles out underwater, science causes those smelly fart molecules to disperse and dissolve in ways that assault your nostrils. Chlorine and good manners can only do so much!

But now you understand exactly WHY your swimming farts get so stinky. Knowledge is power when it comes to butt bubbles! With preparation and a little courtesy, poolside gas can be managed without too much embarrassment or nose plugs required.

Here‘s hoping this guide has you excited to dip back into the pool or tub soon for a refreshing and fume-free summer of fun ahead! Just maybe avoid the beans beforehand.
