Water can exist in two phases at once.
Under certain conditions in a vacuum, where it can boil and freeze simultaneously.
Bananas are radioactive.
These everyday fruits contain a small amount of radioactive potassium, making them naturally radioactive. But don’t worry, it’s harmless!

These celestial objects are so dense that just a teaspoon of one would weigh about 6 billion tons on Earth.
Humans share 60% of their DNA with bananas.
It’s hard to believe, humans and bananas have a surprising amount of DNA in common.
Sharks have been around longer than trees.
Sharks have existed for around 400 million years, while trees only appeared around 350 million years ago—making sharks older than trees.
A day on Venus is longer than a year on Venus.
Venus has such a sluggish rotation that a single day on Venus is longer than its year. It takes 243 Earth days to complete one day!
The octopus has a triple-hearted circulatory system.
Octopuses have three hearts—two pump blood to the gills, while one pumps it to the rest of the body.
The Eiffel Tower can grow taller in the summer.
The Eiffel Tower can grow up to 6 inches taller in summer due to the expanding properties of metal when it’s heated.
Diamonds literally fall from the sky on some planets.
On the gas giants of Jupiter and Saturn, extreme pressure can turn methane into diamonds, resulting in literal diamond rain.
The Mpemba effect makes hot water freeze quicker.
It defies logic, hot water can freeze faster than cold water under certain conditions—this phenomenon is known as the Mpemba effect.
Earth’s trees outnumber the stars in our galaxy.
Scientists estimate there are over 3 trillion trees on Earth, which is more than the 100–400 billion stars in the Milky Way galaxy.
Honey never spoils.
Archaeologists have found honey in ancient tombs that is still good to eat, proving that it can last thousands of years without spoiling.
