Fascinating Nature and Science Facts You’ll Want to Share

Did you know how igloos work?
An igloo is the traditional home of the Inuit people, made from bricks of snow and shaped like a dome. It might seem strange, but snow can act as great insulation. A well-built igloo can stay up to 40 degrees warmer inside than the freezing air outside!

Did you know what causes ocean storms?
When strong winds blow across the sea, they can create giant waves called storm surges. These waves can grow as tall as a 2 or 3-story building around 26 feet high!

Did you know how ID numbers are checked?
The last digit of an identity number isn’t just random. It helps make sure the number is typed or written correctly. Using a system called the Luhn Algorithm, certain digits are multiplied, others are added, and the total is rounded up to the nearest 10. The last digit fills in the gap. For example, if the sum is 42, it’s rounded to 50, so the last digit is 8.

Did you know there's a fish that hunts by spitting?
The archerfish, also known as the "spitting fish," has a unique way of catching its food. It gathers water in its mouth and spits it out with amazing aim and force to knock insects off leaves above the water. When the insect falls in, the fish gobbles it up!

Did you know why mountaintop snow doesn’t melt?
Even in summer, the tops of high mountains stay cold. The higher you go, the colder it gets. That’s why snow often stays on the peaks, even when it’s warm down below.

Did you know how sandpaper is made?
Sandpaper is rough paper coated with tiny grains, usually made from quartz or sifted sea sand. The smoother the sandpaper, the smaller and finer the grains.

Did you know which insect is the best jumper?
The froghopper, a type of cicada, holds the record for jumping height. It can leap 110 times its own body size! That’s like a person jumping over a skyscraper. Its jump creates a force about 400 times Earth’s gravity, while a human jump only reaches about 2 to 3 times gravity.
