Trivia quiz with useful tips to know: fun facts that come in handy at school or at home [for kids]

lick the upper lip

When you yawn during class, you can’t help but feel sorry toward the teacher, right? So let’s remember a way to stop yawning! It’s said that if you lick your upper lip with a quick swipe when you feel a yawn coming on, it will stop. It sounds a bit strange, but it really works—give it a try.

Press the ear canal

You know how sometimes hiccups just won’t stop? You might even get hiccups during class and feel embarrassed. It’s said that putting your fingers into your ears and pressing firmly for several tens of seconds stimulates the nerves deep in the ear and can help stop hiccups.

cool the forehead

Everyone has probably experienced that sharp, ice-cream headache while eating ice cream or shaved ice! This happens because the sudden cooling in your mouth increases blood flow and causes blood vessels to dilate, and because nerves in the throat get stimulated. Cooling your forehead can help constrict those dilated vessels, and the added sensation can ease the sharp pain. Try pressing the ice cream or shaved ice container directly against your forehead.

Apple

Kiwifruit is popular, and the commercials featuring Zespri’s Kiwi Brothers are a hit too. It’s a sweet-and-tangy, delicious fruit, but the kiwis you buy are often not ripe yet and can take a while to become ready to eat. If you store kiwis in a bag together with an apple, they’ll ripen faster. That’s because apples release a substance called ethylene, which promotes the ripening of kiwis. Grapefruit and cucumbers, on the other hand, release little to no ethylene.

Really

Here’s a handy tip to make milk—which many people drink every day—taste even better. If you give it a shake before drinking, milk actually becomes more delicious. That’s because the fat and protein in milk don’t fully dissolve; they remain suspended as particles. Shaking mixes these components thoroughly, bringing out milk’s original flavor. Specifically, it’s said to enhance its sweetness and umami.

newspaper

If you crumple up some newspaper, dampen it, and use it to wipe your windows, they’ll get really clean even without detergent. The ink in the newspaper helps break down dirt and is said to add a bit of shine as well. After wiping with the damp newspaper, wiping once more with dry newspaper as a finishing touch makes it even more effective.
