The London Marathon Gave Out These Water Bubble Pods, Replacing 200,000 Water Bottles
Here's something to chew on. Can a gulp of water help save the planet? If you're drinking *and* eating your water at the same time, the answer may be yes.
The tasteless packaging is made from brown seaweed that biodegrades naturally in four to six weeks.
The Lowdown
A start-up company called Skipping Rocks Lab has created a "water bubble" encased in an edible sachet that you can pop in your mouth whole. Or if you're not into swallowing it, you can tear off the edge, drink up, and toss the rest in a composter. The tasteless packaging is made from brown seaweed that biodegrades naturally in four to six weeks, whereas plastic water bottles can linger for hundreds of years.
The founders of the London-based company are determined to "make plastic packaging disappear." They had two foodie inspirations: molecular gastronomists and fruit. They tried to emulate the way chefs used edible membranes to encase bubbles of liquid to make things like fake caviar and fake egg yolks; and they also considered the peel of an orange or banana, which protects the tasty insides but can be composted.
The sachets can also contain other liquids that come in single-serve plastic containers -- think packets of condiments with takeout meals, specialty cocktails at parties, and especially single servings of water for sporting events. The London Marathon last month gave out the water bubble pods at a station along the route, using them to replace 200,000 plastic bottles that would have likely ended up first in the street, and ultimately in the ocean.
Next Up
The engineers and chemists at Skipping Rocks intend to lease their machines to others who can then manufacture their own sachets on-site to fill with whatever they desire. The new material, which is dubbed "Notpla" (not plastic), also has other applications beyond holding liquids. It can be used to replace the plastic lining in cardboard takeout boxes, for example. And the startup is working on additional materials to replace other types of ubiquitous plastic packaging, like the netting that encases garlic and onions, and the sachets that hold nails and screws.
Edible water bubbles may be the future of drinks at sporting events and festivals.
Open Questions
One hurdle is that the pods are not very hardy, so while they work fine to hand out along a marathon route, they wouldn't really be viable for a hiker to throw in her backpack. Another issue concerns the retail market: to be stable on a shelf, they'd have to be protected from all that handling, which brings us back to the problem the engineers tried to solve in the first place -- disposable packaging.
So while Skipping Rocks may not achieve their ultimate goal of ridding the world of plastic waste, a little progress can still go a long way. If edible water bubbles are the future of drinks at sporting events and festivals, the environment will certainly benefit from their presence -- and absence.
How to have a good life, based on the world's longest study of happiness
What makes for a good life? Such a simple question, yet we don't have great answers. Most of us try to figure it out as we go along, and many end up feeling like they never got to the bottom of it.
Shouldn't something so important be approached with more scientific rigor? In 1938, Harvard researchers began a study to fill this gap. Since then, they’ve followed hundreds of people over the course of their lives, hoping to identify which factors are key to long-term satisfaction.
Eighty-five years later, the Harvard Study of Adult Development is still going. And today, its directors, the psychiatrists Bob Waldinger and Marc Shulz, have published a book that pulls together the study’s most important findings. It’s called The Good Life: Lessons from the World’s Longest Scientific Study of Happiness.
In this podcast episode, I talked with Dr. Waldinger about life lessons that we can mine from the Harvard study and his new book.

More background on the study
Back in the 1930s, the research began with 724 people. Some were first-year Harvard students paying full tuition, others were freshmen who needed financial help, and the rest were 14-year-old boys from inner city Boston – white males only. Fortunately, the study team realized the error of their ways and expanded their sample to include the wives and daughters of the first participants. And Waldinger’s book focuses on the Harvard study findings that can be corroborated by evidence from additional research on the lives of people of different races and other minorities.
The study now includes over 1,300 relatives of the original participants, spanning three generations. Every two years, the participants have sent the researchers a filled-out questionnaire, reporting how their lives are going. At five-year intervals, the research team takes a peek their health records and, every 15 years, the psychologists meet their subjects in-person to check out their appearance and behavior.
But they don’t stop there. No, the researchers factor in multiple blood samples, DNA, images from body scans, and even the donated brains of 25 participants.

Dr. Waldinger is Clinical Professor of Psychiatry at Harvard Medical School, in addition to being Director of the Harvard Study of Adult Development. He got his M.D. from Harvard Medical School and has published numerous scientific papers he’s a practicing psychiatrist and psychoanalyst, he teaches Harvard medical students, and since that is clearly not enough to keep him busy, he’s also a Zen priest.
His book is a must-read if you’re looking for scientific evidence on how to design your life for more satisfaction so someday in the future you can look back on it without regret, and this episode was an amazing conversation in which Dr. Waldinger breaks down many of the cliches about the good life, making his advice real and tangible. We also get into what he calls “side-by-side” relationships, personality traits for the good life, and the downsides of being too strict about work-life balance.
