One electron at a time. One dot at a time. So where do the stripes come from? 🤔

Join Cone and Driver for “Quantum Queue,” a science experiment where tiny particles deliver a big surprise! With help from Wattz, Pip, Prudence, Static, and the spinning genius Loophole, the gang explores one of the most fascinating experiments in physics.

In the double-slit experiment, electrons travel toward a barrier with two narrow openings. Each detected electron leaves a single dot on a screen. Yet even when electrons are sent individually, many dots gradually form an interference pattern: alternating bands of frequent and rare arrivals. This behavior has been demonstrated in real experiments. Read about the research.

Why is that remarkable? Electrons don’t behave like tiny marbles following ordinary trajectories. Quantum mechanics describes the alternatives using probability amplitudes, which combine like waves. They reinforce in some places and cancel in others, shaping where electrons are likely to land. The theory predicts the overall pattern without predicting each individual landing with certainty.

When a detector reliably records which opening each electron passes through, the interference disappears. Measurement involves a physical interaction that changes the experimental conditions—even if nobody reads the record. Simply watching the final screen doesn’t have that effect.

The deeper implication: our everyday ideas about particles, waves, and measurement are incomplete at quantum scales. The experiment reveals wave-like interference and localized particle detections in the same system. It does not establish that human consciousness controls reality. Explore the physics in the Feynman Lectures.

Three minutes of quantum physics, curious questions, and questionable crowd control.

What looks like a hole in space may be exactly where a star’s story begins. 🌌

In “The Darkest Nursery,” Part 2 of Cone and Driver’s ten-part How to Build a Star series, Cone has returned to the stellar nursery—and he is not impressed with the lighting.

Driver explains that the enormous dark patch is not empty. Dust inside the molecular cloud is blocking the visible light from stars behind it. Hidden within the cloud are colder, denser pockets called cores: possible starting places for new stars.

Along the way, Cone and Driver explore:

• How moving gas can gather into filaments and dense cores
• Why “dense” in space can still mean far thinner than Earth’s atmosphere
• How cold gas produces less thermal pressure to resist gravity
• Why infrared telescopes can reveal clues hidden from human eyes
• Why seeing a dark core does not guarantee that a star will form
• How the starting conditions of a star can eventually affect an entire planetary system

Cone came looking for a night-light. Instead, he found a business with zero stars—and excellent potential.

This episode focuses on the quiet stage before gravitational collapse. The cloud is still cold, dark and starless, but the ingredients are gathering in places where gravity may eventually gain the advantage.

Next in the series: Part 3, “A Total Collapse,” where Cone and Driver investigate what finally makes a dense core begin falling inward.

Cone wants a night-light. Naturally, he goes straight to a stellar nursery. 🚀

In “Some Assembly Required,” episode 1 of the ten-part Cone and Driver series How to Build a Star, a simple shopping trip becomes an adventure through a vast molecular cloud.

Driver explains how cold clouds of hydrogen, helium, and dust provide the ingredients for stars—including the Sun. Cone would like to know why his lamp arrived unassembled, whether the dust under his bed counts, and where the screwdriver goes.

Along the way, discover:

  • What a molecular cloud is and why hydrogen atoms often come in pairs.
  • Why the birthplace of a hot star can be colder than a freezer.
  • How an enormous cloud of incredibly thin gas can contain enough material for many stars.
  • Why a light-year measures distance—and why interstellar delivery might take a while.

This episode begins the journey with the ingredients. Next up: the dense, dark pockets where a star’s formation can begin.

Could that dark patch in space be hiding a future star? 🚀

Cone and Driver suit up to explore Bok globules: cold, dark clouds of gas and dust that can become stellar nurseries. Cone thinks someone has left a hole in the universe. Driver has a much brighter explanation.

Discover how gravity gathers gas, how a collapsing cloud forms a protostar, and how nuclear fusion eventually powers stars like our Sun. Along the way, they explore how infrared telescopes help astronomers investigate what the dust is hiding.

Cone, naturally, sees all of this as a scientific reason to stop cleaning his room.

A few facts from this corner of the cosmos:

  • Bok globules look dark because their dust blocks visible light from stars behind them. Some form new stars; others eventually disperse. NASA explains Bok globules.
  • One real example, Barnard 68, contains about twice the Sun’s mass and has been measured at approximately −257°C. That is some seriously chilly star-making material. Explore Barnard 68 with ESO.
  • A protostar initially shines using energy released during its collapse. Sustained hydrogen fusion comes later, if it grows massive enough. Read about how stars form.

Millions of years of star formation. One very itchy helmet.
Cone wants to measure the Earth for a belt. His tape measure is three meters long. This is a problem.

Driver has a better idea: two sticks, two shadows, and one line of arithmetic.

On a beach, Cone and Driver stand a one-meter stick upright and compare its shadow with an identical stick 800 kilometers due south. At the southern beach the midday Sun is almost directly overhead and that stick casts no shadow at all. Theirs casts one about twelve and a half centimeters long, which works out to an angle of about 7.2 degrees.

The Sun is so far away that its rays reach both beaches very nearly parallel. So the 7.2 degrees isn't the sunlight spreading out. It's the Earth curving between the two sticks.

Everything after that is one line of math:

360 / 7.2 = 50, so the two beaches are one fiftieth of the way around the planet 800 km x 50 = 40,000 km, the circumference of the Earth.  

A Greek scholar named Eratosthenes worked this out more than 2,200 years ago using the Sun at Syene, a column at Alexandria, and no satellites whatsoever. It is still one of the best things anyone has ever done with a stick.
What happens when a bridge finds its favorite beat?

Cone and Driver head onto a massive suspension bridge to explore resonance—the science of how small, repeated forces can create surprisingly large movements when their timing matches an object’s natural frequency.

Using a miniature bridge and hanging weight, they discover why pushing a swing at exactly the right moment makes it travel higher, how bridges safely flex, and why engineers use dampers—also known in Cone’s extremely official vocabulary as “anti-wiggle machines.”

Wild moments from bridge history:

  • In 1831, marching soldiers increased the vibrations of England’s Broughton Suspension Bridge and helped trigger the failure of an already weak chain connection. The incident inspired orders for soldiers to break step while crossing bridges. Manchester Victorian Architects
  • London’s Millennium Bridge began swaying sideways when crowds crossed on its opening day in 2000. Engineers studied the pedestrian–bridge feedback and installed dampers before it reopened. Ingenia
  • Washington’s Tacoma Narrows Bridge famously twisted apart in the wind in 1940. Although it is often called an example of ordinary resonance, the official explanation identifies torsional flutter, a more complicated interaction between wind and the moving bridge. Washington State Department of Transportation
  • In 2010, Russia’s Volgograd Bridge developed such dramatic wind-driven waves that people nicknamed it the “Dancing Bridge.” It was inspected and later equipped with vibration-control systems. Engineering study.

Can Cone keep the bridge steady—or has he always been structurally responsible?
What happens when a spoon breaks in half without actually breaking?

In The Spoon That Broke in Half, Cone discovers a badly bent spoon sitting in an apparently suspicious glass of water. Driver insists that the spoon is perfectly straight, which leaves Cone with only two possibilities: either the water is attacking the silverware, or their eyes are bending the truth.

The real culprit is refraction—the change in direction that can happen when light travels from one transparent material into another. Light reflected from the submerged part of the spoon passes through the water and then into the air before reaching our eyes. Because its path changes at the boundary, the underwater part appears shifted, making the spoon look bent at the waterline.

You can try the experiment yourself by placing a spoon, pencil, or drinking straw in a clear glass of water and looking at it from the side. Change your viewing angle and watch the apparent bend change too. If you are using a glass container, have a grown-up nearby.

Quick refraction facts Light travels at different speeds through different materials. In water, it travels at roughly three-quarters of its speed in a vacuum. Light changes direction most noticeably when it crosses a boundary at an angle. If it enters straight through—perpendicular to the surface—its speed changes, but its direction does not.

Refraction makes swimming pools appear shallower and can make a fish look closer to the surface or slightly displaced from its real position.

Your eyes, cameras, magnifying glasses, microscopes, and telescopes all use curved lenses to refract and focus light. Rainbows involve refraction too. Sunlight bends as it enters a raindrop, reflects inside it, and bends again as it exits. Different colors bend by different amounts, spreading white light into a spectrum.

No spoons were harmed during this investigation. One glass remains under questioning.
Can Cone and Driver calculate the speed of light without racing a single beam?

In this episode, they connect three experiments: an electric-force measurement, a magnetic-force measurement, and a microwave-and-chocolate test. The first two reveal the electric and magnetic properties of empty space, which Maxwell’s equations combine to predict a speed near 300 million metres per second. The microwave experiment then provides an independent estimate by measuring the distance between melted chocolate spots.

Microwaves and visible light are both electromagnetic waves—their wavelengths are simply very different. The exact speed of light in a vacuum is 299,792,458 metres per second, although these low-budget experiments produce estimates rather than perfect measurements.

No photons were raced. The dessert was peer-reviewed.
Cone has finally returned his library book. Unfortunately, it is 400 years overdue.

Driver expects a fine. Cone sees the enormous red word “FINE” and accepts the library’s apology. What follows is a completely reasonable explanation involving historical corrections, a brief reign as King of a Sandwich, one overly literal dragon, and the destruction of a perfectly good returns desk.

Can Cone return The Complete History of Everything before the late fee inherits property? Or will he prove that the book is not overdue because everything has not finished happening yet?

Check out a few strange but true library facts:

📚 George Washington borrowed The Law of Nations in 1789. A replacement copy was finally returned 221 years later—and the original overdue fine was never paid. Cone calls that presidential borrowing.

⛓️ Some medieval libraries chained valuable books to their shelves. The books were placed with their page edges facing outward so the chains would not become tangled. They were extremely well-bound.

🔍 The smallest book in the Library of Congress is only 1/25 of an inch square—roughly the size of a printed period. The largest is approximately five feet tall and seven feet wide. One is easy to lose. The other can become the library.
Cone and Driver are stuck inside a vending machine—or, according to Cone, they’re simply “in stock.”

When Driver is mysteriously selected, Cone must cancel the order before his best friend gets dispensed. Unfortunately, Cone is more concerned about why Driver costs $1.25 while he has been marked down to twenty-five cents.

Prepare for exact change, questionable nutrition labels, pressing matters and enough snack puns to jam the entire machine!

Fun vending-machine facts:

  • One of the earliest known vending-machine designs was created by Hero of Alexandria during the first century. A coin landed on a lever, opened a valve and dispensed a measured amount of holy water.
  • Modern vending machines began appearing in England during the 1880s. Percival Everitt’s 1883 machines sold postcards, envelopes and notepaper at railway stations and post offices—because apparently snacks had not been selected yet.
  • Vending machines arrived in the United States in 1888, when the Thomas Adams Gum Company placed machines selling chewing gum on New York City transit platforms. America’s vending-machine industry began by sticking to what it knew.

Will Driver escape? Will Cone finally be selected? Will either of them receive exact change? Watch to find out—and remember: they’re not stuck. They’re in stock!
Cone has finally admitted the truth: he may have started the Trojan War with one extremely argumentative apple.

Now he plans to end ten years of conflict with a gigantic wooden apology horse. Unfortunately, the horse is hollow, full of seats, covered in air holes, and equipped with enough “Greeks-room” to rest an army.  Can Driver uncover the problem before Troy accepts Cone’s suspicious present—or will Cone’s peace offering become history’s worst surprise package?

🏺 FUN TROJAN WAR FACTS:
  • The ancient site identified as Troy stands at HisarlÄąk in modern-day TĂźrkiye and contains evidence from roughly 4,000 years of history.
  • Tradition places the Trojan War around the 13th or 12th century BCE, although historians still debate how much of the famous story reflects a real conflict.
  • Homer’s Iliad ends before Troy falls. The wooden horse is mentioned briefly in the Odyssey, while its most famous detailed account appears centuries later in Virgil’s Aeneid.
  • Archaeologists have uncovered multiple settlements built one over another at Troy—meaning the city was repeatedly rebuilt long before Cone arrived with his fruit basket.
