The Explainer General
Most disasters are a cascade: small failures and minor circumstances, one leading to another, blossom into a cataclysm. On January 16, 1919, a cascade of tremendous size was poised above Boston’s North End.
The weather was one factor: unusually warm for winter.
Purity Distilling Company fermented and distilled molasses to make rum and alcohol. The 18th Amendment to the United States Constitution, prohibiting sales of alcoholic beverages, was due to be passed the very next day. This may have prompted Purity to collect as much molasses as possible.
The enormous tank holding the molasses was about 50 feet tall and 90 feet in diameter, holding 2,300,000 gallons. It was poorly built of thin steel painted brown to hide its leaks. Local families often collected some of the dripping molasses to sweeten their food. The unseasonably warm temperature quickly rose from 2° F (-16.7° C) to 40° F (4.4° C), expanding the liquid, and natural fermentation produced CO2 increasing tank pressure.
Just after noon, North End families felt the ground shake and heard a sound like a machine gun— the tank’s rivets popping out. The big tank exploded, sending a 25-foot wall of molasses roaring down the hill toward Commercial Street at about 35 miles an hour. In front of the molasses went a blast of air that blew some folks off their porches and tumbled others along the street like rag dolls. Homes and buildings were destroyed, smashed from their foundations. Horses pulling wagons were swept away. The steel girders of the Boston Elevated Railway were buckled, knocking a rail-car off the tracks.
Twenty-one people were killed and more than a hundred were injured. Many were saved by Massachusetts Maritime Academy cadets who rushed off their docked training vessel and plunged into the brown goo to rescue people. It’s difficult to know how many dogs, cats and horses died.
As you can imagine, the clean-up was awful. Firehoses from hydrants and harbor fireboats washed away as much as possible. Boston Harbor was brown for months. Sightseers tracked the goo back to homes, into hotels, onto pay-phones and onto doorknobs. Everything Bostonians touched was sticky for months.
Some say that on a hot summer day along the North End’s docks, the sickly sweet smell of molasses lingers. Bostonians can smile at the Great Molasses Flood now, but in January of 1919, that cascade of disasters was deadly serious.

"Connecting Scientists and Kids”
Only you can prevent forest fires! At least that’s what Smokey Bear taught me growing up. His message? All forest fires are bad, and we’re helping nature by putting them all out.
Recently, I met a scientist who’s made me rethink this negative message about natural wildfires. His name is Dick Hutto and he’s a biology professor at the University of Montana. “There are two kinds of fires,” Dick explains. “The ones that burn down your house or kill your neighbor are bad, bad, bad. The other ones can be the greatest things in the world.”
To prove his point, Dick took me to the Black Mountain burn area, near my home in Missoula, Montana. A severe forest fire burned through this area only ten years ago, and thousands of blackened trees still stand like sentries across the landscape. Surprisingly, this charred landscape explodes with life. Tens of thousands of new tree saplings reach for the sky. Elk and deer graze on the fresh grass growing in the newly-opened areas. More than anything, the songs of birds fill the burned forest.
In his research, in fact, Dick discovered that dozens of bird species love fresh burn areas. In the West, 15 bird species prefer burned forests to all other habitats! Woodpeckers pave the way. As soon as a forest burns, legions of wood-boring beetles descend on the forest and lay their eggs in the dead trees. Three-toed, Hairy, and Black-backed Woodpeckers follow and begin devouring the newly-hatched beetle grubs. They also chisel out their own nest holes—holes that are used by Mountain Bluebirds, American Robins, Black-capped Chickadees, and many other species. Because of burned forests, these birds find food and shelter. They also find safety. How?
Green forests abound with squirrels and chipmunks—animals that feast on bird eggs. A severe forest fire, though, clears out the small mammals. That means that birds can raise their young much more safely.
But listen, don’t take my word for it—or even Dick Hutto’s.
To learn more about the benefits of fire, throw a water bottle, lunch, a bird guide, and a pair of binoculars in your backpack and go visit a burn area for yourself. You will be astonished by what you see. Take a notebook or a camera along, too. Part of the fun of discovering our planet is sharing what you see. By doing so you’ll help others realize the importance of natural wildfires and burned forest—and help create a healthier, more interesting world.
Sneed Collard III has written a book about the birds that thrive in burn areas. Fire Birds shows how dozens of bird species not only survive, but actually thrive in burned areas, depending on burns to create a unique and essential habitat that cannot be generated any other way.

The “Julia Child” of kids’ hands-on science
Dr. Hugh Willoughby, of Florida International University, was one of the first meteorologists to ever fly into the eye of a hurricane. Now the job is done by the Hurricane Hunters—a team of pilots, navigators and meteorologists who fly into these dangerous storms to help keep us safe. Here’s what I learned when I interviewed Hugh Willoughby:
What is a hurricane eye?
Hurricanes are circular storms so the wind blows around in a circle. The eye is the center of a hurricane. If a circular storm doesn’t have an eye, it is not a hurricane—it’s a tropical storm. The eye is surrounded by a ring of clouds called the eyewall. Within the eye, there is a calm area that is cloudless all the way up to space. The winds are strongest just at the inner edge of the eyewall, which is composed of violent thunderstorms with strong updrafts and downdrafts. The hurricane pinwheels out from the eyewall as spiral bands of wind and rain, which stretch for miles. When a hurricane’s eye passes over land, the storm suddenly stops and the sun comes out. But the relief is short-lived as the other side of the storm soon slams into the area.
How do Hurricane Hunters help us?
Hurricane Hunters fly into the eye of hurricanes that are heading towards our shores to help predict where the storm will make landfall. On every mission they must find the center of the storm at least twice and at most four times over a period of several hours because the change in position of the center of the eye tells us the direction the storm is moving and how fast it is moving. They also drop packages called dropsondes that contain measuring instruments for air pressure, humidity, and wind speed at the eyewall. These measurements tell us the destructive power of the storm or its “category.” During a hurricane season (from June 1 to November 30) the Hurricane Hunters and their fleet of ten airplanes can get data on three storms, twice a day. So flying into a hurricane’s eye is pretty routine for them.
Is it dangerous?
The planes can easily handle changes in air pressure and wind speeds that create “bumps” and it can be pretty bumpy going through the eyewall. But, in more than sixty years there have been only four accidents. All on board agree that the view of the eyewall from inside the eye is worth it! The plane has transported them inside nature’s most magnificent amphitheater.

Harvey and Irma have alerted everyone to the dangers of a hurricane. We can predict the course of a hurricane by flying into a hurricane and repeatedly measuring wind speed, humidity, air pressure, and temperature. Here's a video that will give you a taste of what it looks like as you approach an eye wall. It is filmed from a plane penetrating Hurricane Katrina.
