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

Gargle only once with a small amount of water.

After brushing your teeth, rinsing just once with a small amount of water leaves the fluoride from the toothpaste on your teeth, which helps prevent cavities. Be careful—rinsing many times washes the fluoride away! Many people may be rinsing repeatedly to thoroughly wash out the toothpaste, perhaps more than they realize.

hand cream

Have you ever noticed that permanent marker ink ends up on your hands? And it’s so hard to remove that it can be a real hassle. But if you apply some hand cream and rub gently, it comes off easily! The oils in hand cream help lift the marker’s ink. Scrubbing with soap can irritate your skin, so give hand cream a try instead.

Put on a cover

Many people have probably experienced their everyday eraser tearing as they use it. If you cut the corners of the eraser cover diagonally, the pressure is dispersed and it becomes less likely to tear. By the way, some manufacturers sell erasers whose case corners are already cut, so try looking for them in stores!

To have everyone dress the same in order to strengthen unity

School uniforms are designed to foster a sense of belonging by having everyone wear the same clothes and to promote a sense of equality. While there are schools with a more liberal atmosphere that do not have uniforms, schools with uniforms are relatively common in Japan. Some people say that having a uniform means they don’t have to think about what to wear every day and that it helps them get into the mood to study.

the middle seat

On field trips and the like, you often travel by bus, right? But for people who get motion sick, that time can be rough. That’s why I want to share which seats are less likely to make you carsick. In fact, there are seats on a bus that tend to cause less motion sickness—around the middle of the vehicle. Seats near the middle aren’t directly over the tires, so there’s less vibration, making motion sickness less likely.

cold-weather gear

As a useful tip for disasters, a raincoat is a great item to include in your evacuation kit. Not only can it be used as rain gear when it’s raining, but it also works very well as protection against the cold!

morning

The morning hours are well-suited for studying. In particular, the first three hours after waking are said to be the brain’s “golden time,” when concentration and thinking ability are heightened. There’s even the term “morning activities,” so if staying up late is tough for you, why not try going to bed early, getting up early, and putting that time into studying?
