The things we use every day often have clever designs we never notice. From kitchen tools to tech gadgets, manufacturers add small details that make life easier — if you know what to look for.

Here are nine hidden features in common items that might surprise you.

1. The Hole in Pot Handles

That little hole at the end of your pot or pan handle isn’t just for hanging. It’s also the perfect spot to rest your cooking spoon while stirring. This keeps your counter clean and prevents burnt pots.

2. The Tiny Hole Near iPhone Cameras

If you look closely at your iPhone, you’ll see a tiny hole near the camera lens. That’s actually a microphone. It picks up sound from the direction you’re filming, helping reduce background noise for clearer videos.

3. The Blue End of Erasers

Remember those two-tone erasers with a pink and blue side? The blue side isn’t meant for ink. It’s designed to erase pencil marks on thicker paper or cardstock. The pink side works best on regular paper.

4. The Loop on the Back of Dress Shirts

Many dress shirts have a small loop on the back, known as a locker loop. Sailors used it to hang shirts on hooks. Later, the clothing brand GANT popularized it in the 1960s among Ivy League students. Some even used it to signal their relationship status — men would remove the loop when they weren’t single anymore!

5. The Hole in Lollipop Sticks

Next time you enjoy a lollipop, check the stick. Many have a small hole at the end. Candy makers designed it so melted sugar flows into the hole as it cools, helping the candy stick firmly and not fall off.

6. The Arrow Beside the Fuel Gauge

Ever noticed a tiny arrow or triangle next to the fuel pump icon on your dashboard? It’s there to show which side of the car your fuel cap is on. No more guessing at the gas station!

7. The Cylinder on Laptop Cables

That little bump near the end of your laptop charger cable is called a ferrite core. It reduces electrical interference, helping your laptop charge smoothly and preventing screen flicker or noise.

8. The Hole in Padlocks

Look at the bottom of a padlock and you’ll often see a tiny hole. It’s there to drain water and prevent rust. You can also use it to apply oil and keep the lock mechanism smooth.

9. The Tic Tac Lid Design

The lid on a Tic Tac container isn’t just for closing it. If you flip it open, you’ll notice a small groove that fits exactly one mint. It’s a clever way to control your portion — one Tic Tac at a time.

A World of Hidden Design

Everyday items are full of smart little details that make them more useful than they appear. The next time you use these objects, you’ll see the thoughtful design behind them — and maybe even feel a little amazed. PRIME
