Unbelivable science facts for kids,  amazing science facts  that will make you surprise:

1. Babies have around 100 more bones than adults

Babies have about 300 bones at birth, with cartilage between many of them. This extra flexibility helps them pass through the birth canal and also allows for rapid growth. With age, many of the bones fuse, leaving 206 bones that make up an average adult skeleton.

2. The Eiffel Tower can be 15 cm taller during the summer

Large structures are built with expansion joints which allow them some leeway to expand and contract without causing any damage.

When a substance is heated up, its particles move more and it takes up a larger volume – this is known as thermal expansion. Conversely, a drop in temperature causes it to contract again. The mercury level inside a thermometer, for example, rises and falls as the mercury’s volume changes with the ambient temperature. This effect is most dramatic in gases but occurs in liquids and solids such as iron too. For this reason large structures such as bridges are built with expansion joints which allow them some leeway to expand and contract without causing any damage.

3. 20% of Earth’s oxygen is produced by the Amazon rainforest

Our atmosphere is made up of roughly 78 per cent nitrogen and 21 per cent oxygen, with various other gases present in small amounts. The vast majority of living organisms on Earth need oxygen to survive, converting it into carbon dioxide as they breathe. Thankfully, plants continually replenish our planet’s oxygen levels through photosynthesis. During this process, carbon dioxide and water are converted into energy, releasing oxygen as a by-product. Covering 5.5 million square kilometres (2.1 million square miles), the Amazon rainforest cycles a significant proportion of the Earth’s oxygen, absorbing large quantities of carbon dioxide at the same time.

4. Some metals are so reactive that they explode on contact with water

There are certain metals – including potassium, sodium, lithium, rubidium and caesium – that are so reactive that they oxidise (or tarnish) instantly when exposed to air. They can even produce explosions when dropped in water! All elements strive to be chemically stable – in other words, to have a full outer electron shell. To achieve this, metals tend to shed electrons. The alkali metals have only one electron on their outer shell, making them ultra-keen to pass on this unwanted passenger to another element via bonding. As a result they form compounds with other elements so readily that they don’t exist independently in nature.

5. A teaspoonful of neutron star would weigh 6 billion tons

A neutron star is the remnants of a massive star that has run out of fuel. The dying star explodes in a supernova while its core collapses in on itself due to gravity, forming a super-dense neutron star. Astronomers measure the mind-bogglingly large masses of stars or galaxies in solar masses, with one solar mass equal to the Sun’s mass (that is, 2 x 1030 kilograms/4.4 x 1030 pounds). Typical neutron stars have a mass of up to three solar masses, which is crammed into a sphere with a radius of approximately ten kilometres (6.2 miles) – resulting in some of the densest matter in the known universe. This is one of the most amazing facts ever.

6. Hawaii moves 7.5cm closer to Alaska every year

The Earth’s crust is split into gigantic pieces called tectonic plates. These plates are in constant motion, propelled by currents in the Earth’s upper mantle. Hot, less-dense rock rises before cooling and sinking, giving rise to circular convection currents which act like giant conveyor belts, slowly shifting the tectonic plates above them. Hawaii sits in the middle of the Pacific Plate, which is slowly drifting north-west towards the North American Plate, back to Alaska. The plates’ pace is comparable to the speed at which our fingernails grow.

7. Chalk is made from trillions of microscopic plankton fossils

Tiny single-celled algae called coccolithophores have lived in Earth’s oceans for 200 million years. Unlike any other marine plant, they surround themselves with minuscule plates of calcite (coccoliths). Just under 100 million years ago, conditions were just right for coccolithophores to accumulate in a thick layer coating ocean floors in a white ooze. As further sediment built up on top, the pressure compressed the coccoliths to form rock, creating chalk deposits such as the white cliffs of Dover. Coccolithophores are just one of many prehistoric species that have been immortalised in fossil form, but how do we know how old they are? Over time, rock forms in horizontal layers, leaving older rocks at the bottom and younger rocks near the top. By studying the type of rock in which a fossil is found palaeontologists can roughly guess its age. Carbon dating estimates a fossil’s age more precisely, based on the rate of decay of radioactive elements such as carbon-14.

8. In 2.3 billion years it will be too hot for life to exist on Earth

Over the coming hundreds of millions of years, the Sun will continue to get progressively brighter and hotter. In just over 2 billion years, temperatures will be high enough to evaporate our oceans, making life on Earth impossible. Our planet will become a vast desert similar to Mars today. As it expands into a red giant in the following few billion years, scientists predict that the Sun will finally engulf Earth altogether, spelling the definite end for our planet.

Fact #1

Because Mercury planet orbits the Sun within Earth's orbit (as does Venus Planet), it can appear in Earth's sky in the morning or in the evening, but not in the middle of the night.

Fact #2

Mercury gets its name from the Roman god of financial gain, commerce, travel, and industry which can be equated with Hermes (in Greek means the messenger of the gods). This planet probably got this name because of the speed that it moves across the sky.

Fact #3

Planet Mercury is 4,878 kilometers wide, making it only slightly bigger than our own moon.

Fact #4

If you were to look up at the sky on Mercury, the Sun would appear to be twice the size then here on our Earth. This is so amazing, probably one of the most Mercury amazing facts we have known.

Fact #5

The rays from the sun are around seven times stronger on Mercury then on Earth.

Fact #6

A year on Mercury is just 88 days long or the orbital period of Mercury around the Sun is about 88 Earth days.

Fact #7

While Planet Mercury is the closest planet to the Sun, Venus is the warmest planet.

Fact #8

In the time it takes Pluto to go around the Sun once, 1028 years have passed away on Mercury.

Fact #9

Mercury is one of only two planets that have no moon orbiting. The other planet is Venus.

Fact #10

The Hubble telescope has never observed Mercury, and never will be able to. This is due to the fact that this planet is too close to the Sun, and light would cause damage the optics and electronics

Fact #11

If you were to weigh 100 kilograms on Earth, you would only weigh 38 kg on Planet Mercury.

Fact #12

Mercury has a very weak magnetic field. It’s just about 1% of that of Earths.

Fact #13

Only half of Mercury Planet has ever been seen. This is the truth, not jokes that not many people knows.

Fact #14

As of 2012, Mariner 10 and MESSENGER are the only two spacecraft to ever have visited the planet Mercury.

Fact #15

Planet Mercury is the smallest planet in the Solar System. Pluto used to be the smallest, until it was decided it no longer categorized as a planet.

Here are amazing Vietnam facts that can amaze you. Let's enjoy!

1. Vietnam is shaped like the letter “S” 

Our first interesting fact about Vietnam is its shape. We love our funky shaped countries especially ones that resemble glamorous high heels (Italy). We particularly like the shape of Vietnam because S also stands for Stefan and Sebastien.

2. Speed dating began here

The second of seven Vietnam facts are about speed dating. Speed dating might be a recent fad in the west, but it has been a stable of hill tribe life in Vietnam for decades. Hill tribes from all over the regions will meet at ‘love markets’, where the local young single people will come together with the intent of finding a mate.

3. Vietnam is coffee paradise 

Coffee paradise funny images

According to the European Coffee Federation statistics, Vietnam is the world’s second largest coffee-producing nation after Brazil, producing 16% of the world’s total coffee (Brazil’s is 40%). Coffee in Vietnam is incredibly tasty, cheap, and the iced version a refreshing drink to cool you down during the warm, humid months.

4. They have their own sport

Takraw, or kick volleyball, is a traditional sport in Vietnam. The development of traditional Vietnamese sports is vital to the preservation of Vietnamese culture. In this sport, a ball is passed from player to player by hitting it with the head and feet. Takraw also is widely played in Laos, Thailand, Myanmar and Cambodia.

5. Bicycles cover the roads

There are an estimated 10 million bikes on Vietnamese roads, and that number is climbing every year. That means that there is a bike for every 8 people in Vietnam. In the major cities, bikes make up 90% of vehicles on the roads and yet it was only in the last 4 years that the government have made it compulsory to wear a helmet! (Source: factoflife) 

6. Ho Chi Minh's body is on display

Ho Chi Minh (known affectionately as ‘Uncle Ho’) travels 8000 miles every year. This is only peculiar because he has been dead for over 40 years now. The Ho Chi Minh Mausoleum in Hanoi is a strange and interesting place to visit on your travels in Vietnam. His body is on show for the world to see for only 9 months of the year. The Mausoleum is usually shut from September to December as Uncle Ho makes his annual journey to Moscow for ‘maintenance’. Not bad for someone whose dying wish was to be cremated…

7. There are different types of temples

“Pagodas are for worship, temples are for honour.” Vietnam is less famous for its temples than neighbouring Thailand or Cambodia, but they are still a prominent part of its history andculture. But how do you tell the difference between the two during your Vietnam holiday? The Vietnamese pagoda (chua) is regarded as a place of worship where offerings are made. Conversely, the Vietnamese den (temple) is not strictly a place of worship, but more of a monument built to honour a great historical figure.

1. Diet Water

Nearly every beverage has its own diet-friendly alternative, even water. Japanese beverage company Sapporo added "specialized peptide bonds" to their water and sells is under the name "diet water." Of course, regular water is still actually the best diet beverage out there. This is the worst in the list of inventions that are completely useless.

2. Subway Chinrest

Most of the times, people don’t get a seat on the subway so they have to stand, and the neck starts hurting if you keep standing for a long time, therefore, Subway Chinrest was born. 

3. Perfect Eyedrop

Because not having this is the reason eyedrops are hard to put in. This is really an awesomescience invention ever, but who will buy this?

4. Shoe Umbrellas

These pennyloafer parasols make absolutely no sense! Won't a regular umbrella also cover your shoes? Also the umbrellas don't even cover the whole shoe, and the bottoms are going to get wet anyway. On top of all that, why would anyone walk around with these embarrassing eyesores?

5. Noodle Fan

For those impatient eaters that don't want to wait a minute before they dig into their noodles, this bulky fan is one eye-catching solution. We don't see how this would be any more efficient than just blowing on your noodles, though.

6. Picnic Pants

These bulky pants completely fail in both form and function. Not only are these saggy pants absolutely hideous to look at, but trying to eat off of them requires you to keep your legs completely still. Just get a blanket and save yourself the ridicule. Like to see interesting science facts?

7. Toilet Golf

Not only does it come with a half-moon putting green, but you also get a DND sign explaining to any would-be knockers that you’re engaged in a serious round of putting while emptying your bowls. It is so funny invention for human ever.

8. Screen Privacy Hood

With the screen privacy hood – the only person able to view your screen with a very narrow, woolly and uncomfortable field of view will be yourself. And now nobody will be able to find out what you’re doing, even the NASA.
