Saturn could float in the water.

Saturn is the least dense planet in our solar system. It's only 1/10 as dense as Earth and about 2/3 as dense as water. If you're less dense than water, you can float.

However, Saturn is 95 times as massive as Earth. It's the second most massive planet after Jupiter. Still, the force of gravity on Saturn is only a little more than on Earth. A 100-lb object on Earth would weigh 107 lbs on Saturn.

The smallest monkey in the world is only about 15 cm tall.

Native to the rainforests of northern South America, the pygmy marmoset tops out at an adult weight of approximately 4 ounces! They typically reside in social groups of about 15 members, which consist of a mating couple and all their offspring.

They defend their home area of less than an acre through calling, chasing, and exposing their distinct white genitals.

Mexico City sinks several inches annually.

The city itself drops between 0.2 and 1.3 feet per year! Because Mexico City has one of the world’s largest metropolitan areas, there is an extremely high demand for water.

70% of this water comes from the groundwater beneath the city. But it is being extracted much faster than it can be naturally replaced.

This drastic water deficit has severely weakened the ground upon which the city rests, causing the Mexican capital to sink.

A day is longer than a year on Venus.

It takes 225 Earth days or 7 1/5 months for Venus to make a complete orbit around the sun (that's 1 Venus year). However, it takes 243 Earth days for Venus to spin around its own axis (1 Venus day).

Therefore: 1 Venus year=225 Earth days and 1 Venus day=243 Earth days.

Keywords: Venus., 1 Venus day=243 Earth days.

The magnetic north pole is moving!

Magnetic changes in Earth's core are making the north pole move. The pole is moving about 40 miles toward Russia every year. It's currently located in northern Canada.

The North Pole and the magnetic north pole are not in the same location. The magnetic North Pole is where compasses actually point. Magnetic north, which is the place where compass needles actually point, is near but not exactly in the same place as the geographic North Pole. Right now, magnetic north is close to Canada's Ellesmere Island.

Navigators have used magnetic north for centuries to orient themselves when they're far from recognizable landmarks.

Although global positioning systems have largely replaced such traditional techniques, many people still find compasses useful for getting around underwater and underground where GPS satellites can't communicate.

The magnetic north pole had moved little from the time scientists first located it in 1831. Then in 1904, the pole began shifting northeastward at a steady pace of about 9 miles (15 kilometers) a year.

In 1989 it sped up again, and in 2007 scientists confirmed that the pole is now galloping toward Siberia at 34 to 37 miles (55 to 60 kilometers) a year.

A rapidly shifting magnetic pole means that magnetic-field maps need to be updated more often to allow compass users to make the crucial adjustment from magnetic north to true North.

Did Barbie have a full name? In fact, Barbie's full name was Barbara Millicent Roberts.

The popular doll was given the name after Ruth Handler (wife of Elliot, a co-founder of the Mattel toy company) saw her daughter playing with paper dolls. She took the idea to her husband who then pitched it to the Mattel toy company, and ever since then the doll franchise was an instant success. Barbie's boyfriend Ken also received his name from one of the Handler's children.

India qualified for the 1950 World Cup, but they refused to go.

The reason? Apparently, they didn't really understand what the World Cup was, so they decided not to attend. The official reason given by the All India Football Federation was that there was insufficient practice time and disagreements over team selection.

Indian Football Team captain Sailen Manna had this to say, "We had no idea about the World Cup then. Had we been better informed, we would have taken the initiative ourselves. For us, the Olympics was everything. There was nothing bigger."

In fact, the Indian team had already competed in the Olympics in 1948.

The story that they didn't play because FIFA didn't let them play barefoot is a myth. They competed in the 1952 Olympics while barefoot.

Sealand claims to be the smallest "country" in the world. It's not even made out of land.

The Principality of Sealand is officially a "micronation", which is "an entity that resembles a nation or a state, but which for the most part exists only on paper, on the Internet, or in the mind of its creator". Sealand earns the dubious title of smallest country, with only 550 square meters of area. It's really just an old WWII anti-aircraft platform 7 miles off the English coast.

The Principality of Sealand was founded in 1976 when British Army Major Paddy Roy Bates occupied the old platform and formally declared independence. The independent status of Sealand has never been recognized by any other nation, and it has only been consistently inhabited by Bates and his family. Bates and his wife go by Prince Roy and Princess Joan.

Despite the small size of Sealand, it has gone through a civil war in 1978. It also once burned down in 2006. Also, BitTorrent site The Pirate Bay once tried to buy Sealand in 2007.

In Japan they have square watermelons.

They get square watermelons by growing them inside of square glass cases. That way they can fit easily into a refrigerator, and you can stack things on them. Square watermelons are expensive though (10,000 yen or about $82). Compare that to regular round watermelons which cost about $15-20 in Japan.Farmers in the southern Japanese town of Zentsuji have figured out how to grow their watermelons so they turn out square. It's not a fad. The technique actually has practical applications. "The reason they're doing this in Japan is because of lack of space," said Samantha Winters of the National Watermelon Promotion Board in Orlando, Florida. A fat, round watermelon can take up a lot of room in a refrigerator, and the usually round fruit often sits awkwardly on refrigerator shelves. "You can find two-inch cubes" in groceries, Winters said. "They have watermelon that's cut in quarters and halves. And you can find clamshell containers with fresh-cut watermelon in there as well." Watermelon also can be pureed and poured into ice-cube trays for freezing.

Our sun is so big that 1 million earths could fit inside of it.

Our sun is so big that 1 million earths could fit inside of it. On the other hand, the largest star known to man is called VY Canis Majoris which could house 9,261,000,000 Suns. If VY Canis Majoris were put in our sun's place it would extend past Saturn. VY Canis Majoris can also fit 7×10^15 Earths inside of it (that's 7 with 15 zeros after it.) VY Canis Majoris (VY CMa) is a red hypergiant star located in the constellation Canis Major. At between 1800 and 2100 solar radii (approx 2,500,000,000 to 2,900,000,000 km across or 1,550,000,000 to 1,800,000,000 miles), it is the largest known star and also one of the most luminous known. It is located about 1.5 kiloparsecs (4.6×1016 km) or about 4,900 light years away from Earth. Unlike most hypergiant stars, which occur in either binary or multiple star systems, VY CMa is a single star. It is categorized as a semiregular variable and has an source Wikipedia

James Milne Wilson was born on Leap Day, February 29th and died on Leap Day.

Wilson served as the Premier of Tasmania. He held this position until the day he died, February 29, 1880. Even though Wilson was 68 years old, he died on his 17th birthday.

Every 4 years in our calendar there is a Leap Year (2008 was a Leap Year, and 2012 will be the next one). On a Leap Year, there is an extra day, known as Leap Day, on February 29. Normally February is only 28 days long, so if you are born on a Leap Day your birthday technically comes once every four years.

If two pieces of metal touch in space, they get stuck together PERMANENTLY.

In space, if unprotected pieces of metal touch each other, they stick together permanently.This doesn't happen on Earth, because the oxygen in our atmosphere forms an extremely thin film of oxidized metal on every exposed surface.
The oxidization layer acts as a barrier that conveniently prevents chunks of metal from sticking to other chunks of metal.

In the vacuum of space, however, there is no oxidation layer. If the atoms of two metal objects come in contact with each other, what you suddenly have is one continuous metal object, and a lot of explaining to do to your mission commander.

This is an issue on the space station. Metal tools used outside the station have to be coated with plastic or other materials that will not stick.

If you consider the Universe as a whole, metal objects sticking together at the drop of a hat is the norm. It's only in special places like Earth, with our highly caustic oxygen-rich atmosphere, that we can carry around bare pieces of metal to hit each other with and not have to worry about how inconveniently sticky they are.
