1. The Pencil

Rummaging around in Cathon’s massive collection, Iris finds the perfect pencil to write to her grandpa with. Which leads to the question: Was the lead pencil really invented in a bathtub?

3. The Teddy Bear

It won’t come as a shock to you to learn that Iris’s and Cathon’s teddy bears are polar opposites! But who created this perennially popular stuffed toy? And did you know that a woman in the US has a collection of over 8,000 of them?

4. Stairways

As they climb an impressively long staircase, Cathon notices that her friend Iris isn’t in the best of shape. On the subject of stairs, is it true that the ones in Chand Baori, in India, were originally built for rolling-somersault competitions?

5. The Hot Dog

Hot dogs and the beach: a classic pairing! Between a sea voyage and hot-dog eating competitions, Iris once again amazes us with the quantity of condiments she’s able to ingest in one go! Come to think of it, why exactly is it called a hot dog?

6. The Skates

At the local ice rink, Iris tries out her grandpa’s old skates while a quizzical Cathon looks on. Have you ever wondered what skates looked like before metal blades were developed?

7. The Bathtub

In the spirit of sustainability, Iris offers to leave her bathwater for Cathon—but a minor detail gives her pause. Fun (or maybe not-so-fun) fact: during the Renaissance, people avoided bathing for fear that microbes would get into their bodies!

8. The Banana

Iris whips up a batch of her famous banana smoothies, but Cathon isn’t the biggest fan of her friend’s recipe. Speaking of bananas, word has it that the banana split was invented by one David Stickler, who was an apprentice pharmacist!

9. The Fridge

A devastated Cathon must face a cruel fact: she must bid farewell to her old fridge, which has brought her so many good times. But before the refrigerator was invented, how did people keep their food from spoiling?

10. The Mirror

Cathon is excited to show Iris her latest flea-market find: a new mirror. But is it true that if you break one, you can expect seven years of bad luck?

11. The Pyjamas

When she finds out what kind of sleepwear her friend likes, Iris bursts out laughing! One thing’s for sure, Iris and Cathon don’t subscribe to the same definition of “pyjama party.” Apparently, way back when, wearing these clothes to the beach was the height of fashion

12. The Toothbrush

While brushing her teeth with Iris, Cathon discovers another of her friend’s crazy ideas: instead of toothpaste, Iris uses hot sauce! They go on to explain that before the invention of the toothbrush, people kept their choppers clean using twigs!
