OXYGEN FROM THE WATER
Half of the Earth's oxygen actually comes from the Oceans, not from trees. In the surface of the sea you can find tiny little plants called Phytoplankton (this thing that looks like a cool wallpaper), and they do what plants do: oxygen.
AFTER DEATH FARTS
You fart after you die. Have you seen the movie "Swiss Army Man"? If you didn't, don't do it. It was just an example of how muscles relax after death and generates all kind of noises and farts.

HOT AND COLD
Our ears are prepared to distinguish the sound of hot and cold water. That's because water changes some of its form when it experiences a temperature change. And that's why coffee sounds so good.
Some creatures can live forever. That doesn't mean that they don't die, but they do it due to disease or injury, because they don't actually age in terms of degeneration. Some examples of this are jellyfish and lobsters.

Sunflowers are used to clean nuclear waste, since they absorb the radioactivity from the soil. That also means that sunflowers can get really weird and even glow in the dark.

Octopus have nine brains and three hearts. They have one central brain and one in every arm, one central heart and two hearts especially for the gills. They also have blue blood.

When you take it to a certain point of temperature and pressure, water can be boiled and frozen at the same time. It is called Triple Point, and it is when the substance is in all three different phases (liquid, solid and gas) at the same time.
When you hear that it takes up to eight months to get to Mars you may think that spacecrafts are very slow. But that's wrong. New Horizons, for example, a spacecraft that flew past Pluto, can reach a speed of 36000 miles per hour. That is 66 times the speed of a Boeing 747. That shows how big the space is.
If you forgot your lenses at home you can try this trick that is quite uncomfortable but can help you. Make a pinhole with your hand and look through the hole. Won't give you perfect vision but it actually works!
Solar flares happen all the time on the surface of the Sun. They are flashes of increased brightness, and they can be as powerful as a million atomic bombs. Did I mention that there are solar flares ALL THE TIME?
Female sharks have thicker skin than male sharks. It is an evolution issue, since male sharks tend to bite their couples violently when they are mating. Females don't like to be around males, and we get why.
On average, ocean is about 12 thousand feet deep (3,600 meters), which is the equivalent of eight Empire States one on top of the other. The deepest part of the ocean, however, is 25 Empire States deep.
The human adult body has two hundred and six bones. We emphasize on the word "Adult" because babies are born with two hundred and seventy bones that fuse together when they grow up.
YOUR WEIGHT ON THE MOON
Gravity on the moon is six times the gravity on earth. That means that someone who weighs 150 pounds (68 kilos) on Earth weighs only 25 pounds (11 kilos) on Earth.
Camels can drink up to 113 liters (30 gallons) of water in a few minutes. But, contrary to what we might think, that water is not stored in their lumps, it is stored in the Camel's bloodstream.

Nine out of ten people in the world are left handed. But the actual amazing fact about this is that we still don't know why we have a dominant hand, Why don't we have two equally working hands? There are a few theories but none of them definitive.
Like all other mammal species, human breasts fill with milk when they have a baby to feed. But human breasts are the only ones that are bloated all the time. Scientists don't agree on the cause of this, but they think that it is probably a mating resource: Men might consider that big breast means a big feeder for their babies.
Sunfishes are the heaviest bony fishes in the world. They can grow up to 10 feet (three meters) long, and have an average weight of 1,000 pounds. But the one you see in this picture is actually the heaviest fish ever found, weighing 5,000 pounds.
There's enough DNA in a single person's body to stretch from the sun to Pluto about seventeen times. That means 102 million miles. It would take you more than 100 years to travel that distance by car.
TOO MUCH WATER
According to the United States Geological Survey, there are 332,519,000 cubic miles of water on earth, and 321,002,271 cubic miles are in the ocean. That's enough water to fill 352,670,000,000,000,000,000 gallon sized milk containers.
An average person walks about 125,000 miles in a lifetime (200,000 kilometers). The earth is 25,000 miles round, that means that you can walk around it five times.
A LOT OF NUMBERS

Fleas have a size of about two millimeters. They can jump 130 times it's size, which means a jump of 26 centimeters. In human terms, is a 23,000 meters tall jump.

Skylab was the first american space station. It was built in 1973 and fell to the earth in thousands of pieces in 1979. Thankfully most over the ocean. The astronauts that lived in Skylab grew a few inches due to zero gravity.
