In 1908, an explosion larger than 1,000 atomic bombs flattened an area bigger than Los Angeles—but no crater was ever found. The Tunguska Event remains one of Earth’s biggest mysteries, and today, Gordy breaks down what happened, why it matters, and whether we should be worried about the next one.

🔥 Topics Covered:

• What was the Tunguska Event?

• Why was there no crater?

• The wildest theories (aliens? Tesla?!)

• The real scientific explanation

• Could it happen again? (Spoiler: Yes.)

💡 Coming Tomorrow: The Torino Scale, the ranking system for space rock threats.

There’s a myth that rivers always flow south, but here’s the truth: rivers flow in whatever direction gravity pulls them. The Nile River flows north—not because it’s defying the rules, but because it’s following the land’s natural slope. And it’s not alone. At least 48 rivers in the U.S. flow north, and plenty more around the world.

Today, Gordy clears up this geographical misconception and breaks down why we think of rivers as only moving south.

In 1997, scientists recorded a mysterious deep-sea sound so loud it could be heard across the ocean. The Bloop baffled experts—it was louder than a blue whale, seemingly organic, and no one could explain it. Some believed it was a giant sea monster, an alien spacecraft, or even the awakening of Cthulhu himself.

But the real answer? It’s still weird.

This episode of Smartest Year Ever dives deep into the legend of The Bloop, from wild conspiracy theories to the actual science behind its eerie, Earth-shaking roar. Plus, we’ll play the sound for you—sped up 16x so you can actually hear it. And just because The Bloop got explained, don’t get too comfortable… there are still other unexplained ocean sounds lurking in the depths.

We know more about the surface of the Moon than the deep ocean. So who knows what’s still down there?

A 25-foot tsunami of molasses barreling through Boston at 35 mph? Sounds like something out of a fever dream—but in 1919, it actually happened. The Great Molasses Flood was one of the most bizarre and tragic industrial disasters in U.S. history, leaving 21 dead, 150 injured, and a city covered in sticky chaos.

Gordy takes you through the explosive failure of a poorly built molasses tank, how it wiped out buildings and trapped people like flies in syrup, and why locals swore you could still smell the disaster decades later. Plus, how this catastrophe led to modern safety regulations—after the company tried to blame anarchists.

Was it just a freak accident, or was this disaster boiling up from the start? Find out in today’s episode of Smartest Year Ever.

Before Pepsi was Pepsi… it was Brad’s Drink. Yes, that’s what North Carolina pharmacist Caleb Bradham originally called his soda fountain creation in 1893. A mix of sugar, lemon oil, nutmeg, and other ingredients, it was meant to aid digestion and boost energy. But in 1898, a name change to Pepsi-Cola gave it a modern edge—though ironically, it never contained pepsin.

From near-bankruptcy in the 1920s to a marketing genius move during the Great Depression, this is the surprising story of how one of the biggest soda brands in the world almost had a very different name.

Why does February have only 28 days? And why is it named after an ancient Roman cleansing ritual? This month used to sit at the end of the calendar, acting as a reset button before the Romans moved the new year to January. Then, in a bizarre turn of numerical superstition, February got stuck as the runt of the litter—and even Julius Caesar’s reforms didn’t help.

🔹 The 10-month calendar that came before🔹 The festival of Februa and its purifying origins🔹 Why February was doomed to be short forever

Before Lady Liberty, there was the Colossus of Rhodes, a towering 108-foot statue that once stood as a symbol of strength and victory. Though it fell centuries ago, its influence lived on in Frédéric Auguste Bartholdi’s design of the Statue of Liberty—from her torch to her crown of rays. But their meanings couldn’t be more different.

Today, Gordy explores how an ancient Greek wonder helped inspire America’s greatest icon of freedom.

Canaries in coal mines were no metaphor—they were lifesavers. Gordy explains how miners relied on these birds to detect toxic gases and the extraordinary biology that made it possible. But it doesn’t end there: from bees monitoring pollution to dogs sniffing out cancer, we’re still relying on animals to warn us of unseen dangers.
