Bubbles Aren’t All Bad. Case in Point: Bubbly Tap Water Free Carbonated Tap Water and Other Good Uses of Bubbles

The financial bubble. The housing bubble. Petrochemicals bubbling up in the Gulf of Mexico. And now for a refreshingly different bubbly for the new year—free bubbly tap water.

It’s now on draft in New York City at places like Peel's and Brooklyn Farmacy. Chez Panisse in Berkeley has offered it since 2007. European cities are dispensing it in an effort to kick the bottled water habit. Venice gave out home carbonation kits to make its so-called “mayor’s water” frizzante and Paris now offers the bubbly—la pétillante—at a public water fountain in Jardin de Reuilly. Could bubbles reinvigorate the campaign for tap water?


“We think it's a terrific approach to delivering safe, affordable water to consumers,” Kate Fried, of Food and Water’s Tap Back the Tap, told me in an email. “We applaud the level of investment in public water infrastructure that it took to launch the [Paris] project. We'd love to see a similar attention to public water systems here in the U.S.”

Bottled carbonated beverages may date to as early as 3150 B.C. in Egypt, Patrick McGovern, author of Ancient Wines and biomolecular archaeologist, told me, but these drinks were without a doubt alcoholic. So aside from naturally occurring carbonated springs, like the one in Vergeze, France where Hannibal is said to found a refreshing drink after crossing the Alps, or the stinky sulfuric mineral baths at health spas, Europeans don’t seem to have been drinking much effervescent water until the 18th century. In 1767, Joseph Priestley developed a way to infuse the effervescence he harvested from beer into other liquids; he did so because he thought (incorrectly) that it could stave off scurvy. Much like today, bubbly then came with an allure of affluence and health.

Now, almost all of the multimillion-dollar bubbly water market is based on bubbles added to water after it’s been pumped out of a well. According to the Food and Drug Adminstration’s rules for water sold in the U.S., only “Sparkling Bottled Water” contains natural carbonation (or, curiously, the same amount of carbon dioxide that the water had at the source.) Perrier was actually forced to remove its “naturally sparkling” label after benzene was found in the company’s bottled water in 1989, apparently because of a manufacturing malfunction, all despite the company’s assertion that it’s bubbles were natural.

So unless you’re drinking Saratoga Springs, imported bubbly, Champagne, or bottle-conditioned beer, chances are your bubbly beverage has been infused with commercial CO2, which is either made by burning liquid petroleum or desulphurised natural gas, or is created as a manufacturing biproduct of ammonia or ethanol. Even with the current obsession with sourcing, it’s hard to image those sources making on the farm-to-table menu.

According to Mark Denny in Froth: The Science of Beer, the world’s total beer manufacturing creates 100,000,000,000,000,000,000 bubbles a year. If these CO2 bubbles sound like a contributor to global warming, consider that even at that astronomical sounding rate, carbonation in beer makes up less than one half of one percent of the global carbon dioxide emissions. If anything, the biggest footprint comes from glass bottles, especially those thick enough to contain the 90 pounds per square inch of pressure inside a bottle of Champagne, shipped halfway around the world.

While there’s still little documented health benefits, the tiny bubbles add a sensory perk to drinking, adding the appearance of acidity and activating our so-called “wasabi receptors.” And whether it’s Perrier’s marketing campaign to yuppies in the mid-1970s or French winemakers in the late 19th century pitching Champagne to noveau riche for the holidays, carbonation still adds one thing: a clean, stylish cachet. Even if it’s just plain old tap.

Will 2011 be the year we finally to tap into bubbly water for the masses? Wait, what if we filled pools with bubbly for the new year? Someone’s already thought of that. As food scientist Dave Arnold told Cabinet magazine:

I’ve always wanted to have a swimming pool filled with seltzer, although it would be quite painful. All your orifices would probably hurt. Imagine opening your mouth and diving into a pool of ice-cold seltzer: for a second, you’d be like, Ahh, and then, Err.

\n

I’ll stick with a glass of bubbly, thanks.

Ahh.

Four black women, Engineers Christine Darden and Mary Jackson, mathematician Katherine Johnson, and computer programmer Dorothy Vaughan, worked as "human computers" at NASA during the Space Race, making space travel possible through their complex calculations. Jackson, Johnson, and Vaughn all played a vital role in helping John Glenn become the first American to orbit the Earth.

They worked behind the scenes, but now they're getting the credit they deserve as their accomplishments are brought to the forefront. Their amazing stories were detailed in the book "Hidden Figures: The American Dream and the Untold Story of the Black Women Mathematicians Who Helped Win the Space Race" by Margot Lee Shetterly, which was later turned into a movie. (Darden was not featured in the movie, but was in the book). Johnson has a building at NASA named after her, and a street in front of NASA's Washington D.C. headquarters was renamed "Hidden Figures Way."

Between Alexa, Siri, and Google, artificial intelligence is quickly changing us and the way we live. We no longer have to get up to turn on the lights or set the thermostat, we can find the fastest route to work with a click, and, most importantly, tag our friends in pictures. But interacting with the world isn't the only thing AI is making easier – now we can use it save the world, too.

A report from Common Sense Media found the average child between the ages of 0 and 8 has 2 hours and 19 minutes of screen time a day, and 35% of their screen time is on a mobile device. A new study conducted by the Cincinnati Children's Hospital published in the journal, JAMA Pediatrics, found exactly what all that screen time is doing to your kid, or more specifically, your kid's developing brain. It turns out, more screen time contributes to slower brain development.

First, researchers gave the kids a test to determine how much and what kind of screen time they were getting. Were they watching fighting or educational content? Were they using it alone or with parents? Then, researchers examined the brains of children aged 3 to 5 year olds by using MRI scans. Forty seven brain-healthy children who hadn't started kindergarten yet were used for the study.

They found that kids who had more than one hour of screen time a day without parental supervision had lower levels of development in their brain's white matter, which is important when it comes to developing cognitive skills, language, and literacy.

The 63-year-old Oakland-Alameda Coliseum, currently branded the RingCentral Coliseum, is one of the most decrepit sports venues in America.

The home to the the NFL's Oakland Raiders (until they move to Las Vegas next season) and MLB's A's, is notoriously known as the Black Hole and has made headlines for its frequent flooding and sewage issues.

One of the stadium's few positive aspects is its connection to public transportation.

We spend roughly one-third of our life asleep, another third at work and the final third trying our best to have a little fun.

But is that the correct balance? Should we spend as much time at the office as we do with our friends and family? One of the greatest regrets people have on their deathbeds is that they spent too much of their time instead of enjoying quality time with friends and family.

Lawmakers in the United Kingdom have made a significant pledge to reevaluate the work-life balance in their country.
