In Disney’s ‘Moana,’ the characters navigate using the stars, just like real Polynesian explorers − an astronomer explains how these methods work
If you have visited an island like one of the Hawaiian Islands, Tahiti or Easter Island, also known as Rapa Nui, you may have noticed how small these land masses appear against the vast Pacific Ocean. If you’re on Hawaii, the nearest island to you is more than 1,000 miles (1,600 kilometers) away, and the coast of the continental United States is more than 2,000 miles (3,200 kilometers) away. To say these islands are secluded is an understatement.
For me, watching the movie “Moana” in 2016 was eye-opening. I knew that Polynesian people traveled between a number of Pacific islands, but seeing Moana set sail on a canoe made me realize exactly how small those boats are compared with what must have seemed like an endless ocean. Yet our fictional hero went on this journey anyway, like the countless real-life Polynesian voyagers upon which she is based.
As an astronomer, I have been teaching college students and visitors to our planetarium how to find stars in our sky for more than 20 years. As part of teaching appreciation for the beauty of the sky and the stars, I want to help people understand that if you know the stars well, you can never get lost.
U.S. Navy veterans learned the stars in their navigation courses, and European cultures used the stars to navigate, but the techniques of Polynesian wayfinding shown in Moana brought these ideas to a very wide audience.
The movie Moana gave me a new hook – pun not intended – for my planetarium shows and lessons on how to locate objects in the night sky. With “Moana 2” out now, I am excited to see even more astronomy on the big screen and to figure out how I can build new lessons using the ideas in the movie.
The North Star
Have you ever found the North Star, Polaris, in your sky? I try to spot it every time I am out observing, and I teach visitors at my shows to use the “pointer stars” in the bowl of the Big Dipper to find it. These two stars in the Big Dipper point you directly to Polaris.
If you are facing Polaris, then you know you are facing north. Polaris is special because it is almost directly above Earth’s North Pole, and so everyone north of the equator can see it year-round in exactly the same spot in their sky.
It’s a key star for navigation because if you measure its height above your horizon, that tells you how far you are north of Earth’s equator. For the large number of people who live near 40 degrees north of the equator, you will see Polaris about 40 degrees above your horizon.
If you live in northern Canada, Polaris will appear higher in your sky, and if you live closer to the equator, Polaris will appear closer to the horizon. The other stars and constellations come and go with the seasons, though, so what you see opposite Polaris in the sky will change every month. https://www.youtube.com/embed/COHwfKusGbs?wmode=transparent&start=0 Look for the Big Dipper to find the North Star, Polaris.
You can use all of the stars to navigate, but to do that you need to know where to find them on every night of the year and at every hour of the night. So, navigating with stars other than Polaris is more complicated to learn.
Maui’s fishhook
At the end of June, around 11 p.m., a bright red star might catch your eye if you look directly opposite from Polaris. This is the star Antares, and it is the brightest star in the constellation Scorpius, the Scorpion.
If you are a “Moana” fan like me and the others in my family, though, you may know this group of stars by a different name – Maui’s fishhook.
If you are in the Northern Hemisphere, Scorpius may not fully appear above your horizon, but if you are on a Polynesian island, you should see all of the constellation rising in the southeast, hitting its highest point in the sky when it is due south, and setting in the southwest.
Astronomers and navigators can measure latitude using the height of the stars, which Maui and Moana did in the movie using their hands as measuring tools.
The easiest way to do this is to figure out how high Polaris is above your horizon. If you can’t see it at all, you must be south of the equator, but if you see Polaris 5 degrees (the width of three fingers at arm’s length) or 10 degrees above your horizon (the width of your full fist held at arm’s length), then you are 5 degrees or 10 degrees north of the equator.
The other stars, like those in Maui’s fishhook, will appear to rise, set and hit their highest point at different locations in the sky depending on where you are on the Earth.
Polynesian navigators memorized where these stars would appear in the sky from the different islands they sailed between, and so by looking for those stars in the sky at night, they could determine which direction to sail and for how long to travel across the ocean.
Today, most people just pull out their phones and use the built-in GPS as a guide. Ever since “Moana” was in theaters, I see a completely different reaction to my planetarium talks about using the stars for navigation. By accurately showing how Polynesian navigators used the stars to sail across the ocean, Moana helps even those of us who have never sailed at night to understand the methods of celestial navigation.
The first “Moana” movie came out when my son was 3 years old, and he took an instant liking to the songs, the story and the scenery. There are many jokes about parents who dread having to watch a child’s favorite over and over again, but in my case, I fell in love with the movie too.
Since then, I have wanted to thank the storytellers who made this movie for being so careful to show the astronomy of navigation correctly. I also appreciated that they showed how Polynesian voyagers used the stars and other clues, such as ocean currents, to sail across the huge Pacific Ocean and land safely on a very small island thousands of miles from their home.

When Did Water Vending Machines Become a Thing?
When did water vending machines appear in America? Explore their history from a 1908 penny water vendor to the refill machines of the 1970s and 1980s.
You’ve probably seen them hundreds of times.
They sit outside supermarkets, convenience stores and shopping centers—or sometimes stand alone in small roadside kiosks. You bring an empty bottle, usually one, three or five gallons, put in some money, push a button and watch purified water pour into your container.
For many people in California, Arizona and other parts of the American West, water vending machines seem like they’ve simply always been there.
But when did we actually start buying water this way?
The answer takes us back more than a century, although the machines we recognize today didn’t really arrive until the 1970s.
The Water Vending Machine’s Surprising Ancestor
The story begins in Boston in 1908 with a man named Lawrence Luellen.
Luellen was working on something that sounds surprisingly modern: a machine that would allow someone to pay a penny and receive a clean drink of water in an individual disposable cup.
At the time, public drinking water was often consumed from a communal cup or metal dipper—a practice that increasingly worried public-health officials because of the potential spread of disease.
Luellen developed a paper drinking cup along with what became known as the Luellen Cup & Water Vendor. The porcelain machine contained water, ice, disposable cups and a place for discarded cups.
For one penny, a customer could get a drink of cold water in a fresh cup.
Historical records at Lafayette College’s Hugh Moore Dixie Cup Company Collection show that Luellen completed work on the vending apparatus in early 1908. His company, the American Water Supply Company of New England, was incorporated on April 4 of that year.
There was just one problem.
The complete water machine was expensive to manufacture.
The company eventually concentrated on selling the disposable cups and cup dispensers instead. Those cups ultimately evolved into one of America’s most recognizable household products—the Dixie Cup.
So although Luellen’s machine wasn’t the five-gallon refill station we know today, the basic idea was already there:
Put money into a machine and receive drinking water.
The Modern Water Vending Machine Arrives
The next major chapter didn’t occur until roughly 65 years later.
According to histories of the water-vending industry, the first practical machines designed to sell purified water in bulk appeared during the mid-1970s.
These were fundamentally different from Luellen’s machine.
Instead of giving customers a cup of water, the new machines treated water—typically municipal tap water—and allowed customers to fill their own reusable containers.
And we have unusually strong evidence that these machines were operating by 1976.
On July 26, 1976, the U.S. Environmental Protection Agency issued a memorandum specifically addressing the regulatory status of water vending machines.
The EPA described machines that filtered and disinfected water with ultraviolet light and then dispensed the treated water into a customer’s own container using a coin-operated mechanism.
In other words, by the summer of 1976, the basic water-refill machine many of us recognize today was already operating in the United States.
Why the 1970s?
The timing wasn’t accidental.
Americans had become increasingly concerned about pollution and drinking-water quality during the 1960s and 1970s.
Congress passed the Safe Drinking Water Act in 1974, establishing a federal framework for protecting public drinking-water supplies. National drinking-water regulations followed during the decade.
Meanwhile, technologies such as filtration, activated carbon treatment, ultraviolet disinfection and eventually reverse osmosis made it practical to build relatively compact systems capable of treating municipal water at the point where it was sold.
The result was a new business opportunity:
Instead of transporting thousands of bottles of water to a store, a vending company could connect a machine to the local water supply, purify that water on site and sell it by the gallon.
Customers supplied the bottle.
California Helps Turn It Into a Business
California became one of the industry’s most important early markets.
One company that would eventually become a major player was founded by Robert G. Miller.
In 1983, Miller established Bottle Water Vending Inc., the predecessor of Glacier Water Services.
The company manufactured water vending machines and placed many of them outside supermarkets. Customers brought their own containers, while participating stores often sold reusable plastic jugs nearby.
The machines treated municipal water using combinations of filtration, reverse osmosis, carbon treatment and ultraviolet sterilization.
The idea caught on quickly.
In 1984, the company expanded from California into Arizona.
Nevada followed in 1986.
By 1987, the company reportedly had nearly 900 water vending machines operating.
Texas and Florida followed in 1988.
The familiar supermarket water-refill station was becoming a significant business.
Then Came the Drive-Up Water Kiosk
Another variation appeared at almost exactly the same time.
In 1984, Lani and Don Dolifka developed what became Watermill Express in Colorado.
Their idea was an automated stand-alone purification kiosk capable of taking municipal water, processing it through multiple purification stages and selling the finished drinking water directly to customers.
Instead of walking into a supermarket, customers could pull up to the kiosk with their bottles.
Later Watermill Express systems were designed to accommodate reusable containers ranging from one to five gallons, using treatment processes including sediment filtration, activated carbon, reverse osmosis, ultraviolet disinfection and ozone treatment.
That basic concept remains familiar today.
Why Five-Gallon Bottles?
The five-gallon container was already well established through traditional bottled-water delivery services.
But refill vending changed the economics.
Instead of purchasing another filled bottle—or waiting for a delivery—a customer could keep the same container and refill it repeatedly.
That eliminated much of the packaging and transportation involved with conventional bottled water.
It also made purified drinking water relatively inexpensive.
Bring the jug.
Buy the water.
Take the same jug home.
Bring it back when it’s empty.
More than four decades later, that’s still essentially how the system works.
So Who Invented the Modern Water Vending Machine?
That’s where the story gets complicated.
There doesn’t appear to be a single universally recognized inventor of the modern bulk purified-water vending machine.
Lawrence Luellen developed an important early coin-operated water vending concept in 1908, but his machine dispensed an individual drink and disposable cup—not gallons of purified water into a customer’s reusable bottle.
The modern bulk-water machine emerged much later, apparently during the mid-1970s, as water-treatment technology and consumer concern about drinking-water quality converged.
By 1976, the EPA was already dealing with the regulatory implications of machines that treated municipal water and sold it through coin-operated dispensers into customers’ own containers.
Entrepreneurs and companies then refined and expanded the idea during the 1980s.
From a Penny Cup to Five Gallons at a Time
The evolution is remarkable.
1908: Put in a penny and receive a cup of cold water.
Mid-1970s: Machines begin treating municipal water and selling purified water in bulk.
1976: The EPA documents coin-operated machines dispensing treated water into customers’ containers.
1983: Bottle Water Vending, the predecessor of Glacier Water Services, begins operations in California.
1984: Glacier’s predecessor expands into Arizona, while Watermill Express develops its automated purification kiosk in Colorado.
Late 1980s and beyond: Water refill machines become increasingly familiar outside supermarkets and at stand-alone locations throughout the United States.
Today, paying a few coins—or tapping a card—and filling a five-gallon jug might seem thoroughly ordinary.
But the machine sitting outside your neighborhood supermarket represents more than a century of evolution in how Americans buy something that once seemed almost unimaginable to sell from a vending machine:
a drink of water.

High Speed Rail
Brightline West Construction Advances, But Opening Timeline Shifts Beyond the 2028 Olympics
Construction continues to expand along Interstate 15 as Brightline West moves closer to connecting Southern California and Las Vegas with 200 mph electric trains, though the opening timeline has shifted to late 2029.
The vision of traveling between Southern California and Las Vegas in about two hours by high-speed rail is steadily becoming more tangible as Brightline West expands construction activity along the Interstate 15 corridor.
Since construction officially began in 2025, work has continued to ramp up in both California and Nevada. Motorists traveling I-15 may have noticed increased construction activity, survey crews, utility work, and periodic lane closures as the project moves from planning into full-scale development.
Construction Is Becoming More Visible
Brightline West’s 218-mile all-electric high-speed rail line will connect Rancho Cucamonga, California, with Las Vegas, Nevada, using the median of Interstate 15 for much of the route.
Current work includes:
- Utility relocation
- Geotechnical investigations
- Site preparation
- Early civil construction
- Continued work around future station locations
As construction progresses, travelers should expect additional traffic impacts along portions of I-15 while crews prepare for bridges, guideways, track installation, and station construction.
A New Timeline
One of the biggest developments since construction began is a revised completion schedule.
While Brightline West was once expected to open before the 2028 Los Angeles Olympic Games, current projections now place passenger service in late 2029.
Large infrastructure projects frequently experience schedule adjustments due to inflation, labor availability, permitting, and supply chain challenges. Although the delay means Olympic visitors are unlikely to ride the line, construction continues to move forward.
Four Passenger Stations Planned
The line will include stations at:
- Las Vegas
- Apple Valley
- Hesperia
- Rancho Cucamonga
Passengers traveling from Los Angeles will transfer to Brightline West using Metrolink at Rancho Cucamonga, creating an important connection between Southern California’s commuter rail network and the new high-speed line.
Fast, Electric Travel
When complete, Brightline West trains are expected to operate at speeds approaching 200 mph, reducing travel time between Rancho Cucamonga and Las Vegas to approximately 2 hours and 10 minutes.
The fully electric trains are being manufactured by Siemens and are designed to offer a comfortable alternative to one of America’s busiest highway corridors.
Looking Ahead
The next major milestones will likely include visible bridge construction, elevated guideways, station buildings, track installation, electrical systems, and eventually testing of the first trainsets.
While passengers will have to wait a bit longer than originally hoped, Brightline West remains one of the most ambitious passenger rail projects currently under construction in the United States.
For Southern California, it represents more than a faster trip to Las Vegas—it could signal the beginning of a new era for high-speed passenger rail in the American West.
