Round 2:
The first sandwich was invented when a medieval French nobleman dropped his roasted meat onto a piece of bread at a feast, and instead of replacing it, he just folded the bread and kept eating. Guests thought it was brilliant.
Reveal: FALSE.
Actual truth: The sandwich was popularized by John Montagu, the 4th Earl of Sandwich (noble title in the Peerage of England), in the 1700s.

Round 3:
The Slinky was invented during WWII when a naval engineer accidentally knocked a tension spring off a shelf and saw it ‘walk’ down instead of falling. It was originally intended to stabilize sensitive instruments on ships.
Reveal: TRUE.
Explanation: He was designing stabilizers, not toys, and the Slinky came from that accidental discovery.

Round 4:
The very first mechanical alarm clock, invented in 1787, could only ring at ONE time: 4 AM. You couldn’t change it. If you needed to wake up at 6, or 9, or noon… too bad. You were waking up at 4.
Reveal: TRUE.

Fun fact:
Adjustable alarm clocks didn’t exist until the 1840s — so people just… woke up at 4.

Round 5:
In Victorian England, toothpaste manufacturers added tiny flecks of gold to toothpaste because people believed brushing with gold would attract good fortune.
Reveal: FALSE.
Victorian toothpaste was usually chalk, soap, or charcoal — definitely not gold.

• 1853, Saratoga Springs, New York, Chef George Crum gets fed up with a fussy customer who keeps sending back his fried potatoes for being ‘too thick.’
• Out of irritation, Crum slices the potatoes paper-thin, fries them until they’re crisp, and piles on the salt.
• Instead of hating them, the customer loves them. Soon, everyone’s asking for the “Saratoga Chips.”
• They spread across the U.S., and by the early 1900s, mass production turns them into the crunchy snack we can’t stop eating.

Fun fact: Potato chips weren’t bagged until the 1920s, before that, they were served in barrels or tins, and people scooped them out with their hands.

Bubble Wrap Origin:
Story arc:

• 1957: Engineers Alfred Fielding and Marc Chavannes try to invent a new kind of cool new textured wallpaper by sealing two shower curtains together.
• They put it through a heat-sealing machine, and the result - a sheet full of tiny air bubbles.
• Their wallpaper idea totally flopped, no one wanted lumpy walls.
• They tried to sell it as insulation for a greenhouse, which also was a flop. 
• But when IBM needed something to protect fragile computer parts during shipping, bubble wrap found its true calling.

Super Glue Origin:
Story arc:

• During World War II, scientist Harry Coover was searching for clear plastic to make precision gunsights. (Devices on a firearm or other ranged weapon that assist in aiming by providing a physical or optical point of reference).
• He tested a chemical compound, cyanoacrylate, that bonded instantly to everything it touched. Total disaster for his experiments.
• Years later, while working on another project, Coover realized that this “failure” was actually the perfect fast adhesive.
• In 1958, Super Glue hit the market, changing home repairs (and finger-sticking accidents) forever.

Fun fact: Super Glue was used in the Vietnam War to close wounds temporarily on the battlefield, literally holding people together.

Popsicles Origin:
Story arc:

• 1905: Frank Epperson, a kid in San Francisco, mixes soda powder and water with a stir stick, and accidentally leaves it out overnight.
• The next morning, it’s frozen solid, stick and all.
• Years later, he rediscovers his childhood accident and patents the “Epsicle,” later renamed “Popsicle.”
• By the 1920s, it becomes a nationwide hit, simple, cheap, and perfectly timed for the hot summers of the Great Depression.

Play-Doh Origin:
Story arc:

• 1930s: A company called Kutol Products made a dough-like cleaner to remove soot from wallpaper.
• When coal heating declined, sales plummeted, until a teacher started using it in art class.
• The company rebranded, added colour and a scent, and Play-Doh was born.
• It became a massive hit, selling over 2 billion cans worldwide.

Summary of the origins discussed:

Why Do We Knock on Wood?

Ancient Celts believed spirits lived in trees. Knocking summoned their protection - or scared away mischief-making spirits.
Over centuries, the superstition spread across Europe and evolved into today’s casual tap tap after a risky statement.
Modern psychology: people still feel “luckier” when they perform rituals, even meaningless ones - like a placebo for luck.
Fun fact: in Turkey, people tug their earlobe and knock twice on wood instead.

The Origins of Saying “Bless You”

Ancient belief: sneezing expelled the soul, leaving the body vulnerable to evil spirits. Saying something protective kept them at bay. 
In the 6th century, during the bubonic plague, sneezing was seen as an early sign of illness. Pope Gregory I suggested “God bless you” as a prayer for protection.
Fun fact: other cultures had their own sneeze responses: in Japan, a sneeze meant someone was gossiping about you. In some Slavic traditions, it confirmed you were telling the truth.

Why Handshakes?
One theory: originated as a way to show you weren’t holding a weapon.
In Roman times, soldiers often shook forearms instead - making sure there was no dagger hidden in a sleeve.
Later, the handshake became a gesture of trust, equality, and greeting.
Fun angle: handshakes have taken a backseat in recent years with the rise of fist bumps, waves, or nods - but the idea of a safe, shared gesture remains.

Candles on Birthday Cakes
Ancient Greeks baked round cakes with candles to honour Artemis, goddess of the moon - the smoke carried prayers to the heavens.
In 18th-century Germany, Kinderfeste celebrated children’s birthdays. A cake was lit at dawn, candles burned all day, and a final wish was made at night.
Over time, this ritual blended into the familiar “Happy Birthday” tradition we know today.
