Flying fish leap out and whip their tails across the water surface to get airborne. Once in the air, they spread out their big side and lower fins. These hard fins catch the wind and help them glide along, up to 400 m in 30 seconds! They may fly to escape ocean predators chasing them in the water, but it doesn't guarantee protection from birds once they're airborne!

They do this to stop other lazy leopards, lions, or hyenas from stealing their food!
Nowadays we buy things with money. But thousands of years ago, there were no money or coins! People gave things or did some work in exchange for other things they wanted , like giving a pot in exchange for some food.
Many museums and historic places don't allow photography. When our camera flashes hit the artwork, it gets damaged. Also, taking pictures can lead to the copying of some rare works of art.
Golf is the only sport ever played on the moon. An astronaut named Alan Shepard used a golf club to hit two golf balls on the Moon. The two balls are probably still there somewhere!
Scientists have found that bees are attracted more towards blue and purple coloured plants. Unlike humans, bees have ultraviolet vision. Certain flowers have ultraviolet markings and patterns that attract a bee and guide them to the nectar. As bees are important pollinators, these findings are an important tool that could help farmers attract more bees towards their crop.
Volleyball was first invented in 1895 for young businessmen who found the new game of basketball too aggressive. It was called mintonette at first, but got its current name when someone saw the volleying nature of the ball passing over the net. The game quickly picked up popularity amongst men and women and spread to other countries as well such as Europe during WWI.
Here is one way to make a guess. Calculate the average weight of all the people, pets, vehicles, food, drink, buildings, waste and so on. The result comes out to be a staggering 125,208,467 tons - equal to 250,000 aeroplanes in one place!
मोथबॉल आमतौर पर रासायनिक नेफ़थलीन से बने होते हैं। ठोस नेफ़थलीन गैसीय अवस्था में सीधे वाष्पित हो जाता है, जिससे धूएं, पतंगे और उनके लार्वा के लिए विषाक्त हो जाता है। ये पतंगे कपड़ों की तरह संग्रहित वस्तुओं को नष्ट कर देते हैं, इसलिए मोथबॉल का उपयोग अलमारी और कंटेनरों में किया जाता है ताकि उन्हें नष्ट किया जा सके। धुएं को सीधे साँस लेने से बचना बेहतर है, क्योंकि यह हमारे लिए हानिकारक भी हो सकता है।
Gas comes from the Greek word 'khaos'. This word initially meant empty space, but it came to mean complete disorder - what we call chaos (KAY-os). Gas molecules have lots of energy and move extremely fast in all directions. Their movement is more chaotic than liquid molecules. Solid molecules barely move at all. J.B. van Helmont was the first person to call gas, 'gas'.
"Sweating the details is more important than anything else."
Pain threshold is the level at which we experience pain and varies from person to person. Studies suggest that it depends on the thickness of a person’s cerebral cortex - the outermost layer of the brain. It was found that a person more sensitive to pain had a thinner cerebral cortex or less grey matter in the areas of the brain related to attention control and thoughts.
A word or number that remains the same when you read it from start or end is called a palindrome. Like 121 or 12321. Did you know, when you multiply numbers containing only 1s with themselves, the result is always a palindrome? For example, 111 * 111=12321 (three 1s), Four 1s (1111 * 1111=1234321). What is 111111111 * 111111111?
The three technology giants HP, Microsoft, and Apple all started in a small garage! HP was started by Bill Hewlett and Dave Packard in 1939 in a garage in Palo Alto (California, USA). Steves Jobs and Steve Wozniak built the first Apple computer in Los Altos (California) in 1976. And finally, Microsoft was founded by Bill Gates and Paul Allen (also 1975) in Boston (USA).
