1 The human stomach can dissolve razor blades:
On the rare occasion that you swallow a razor blade, don’t fret. The human body is more capable than you think. Acids are ranked on a scale from 0 to 7… (anything over 7.5ish is an alkaline and therefore not an acid)….the lower the pH level, the stronger the acid. Human stomach acid is typically 1.0 to 2.0, meaning that it has an impeccably strong pH. In a study scientists found that the “thickened back of a single-edged blade” dissolved after two hours of immersion in stomach acid.

2 A laser can get trapped in water:
Yes, really. A cool thing called total internal reflection is applied when pointing a laser beam through a container of water. When light travels through water, it’s slowed by the heavier particles in water, as described Thus, the laser beam effectively gets “trapped” in the water.

3 Earth’s oxygen is produced by the ocean:
Ever stopped to think where oxygen comes from? Your first thought may be a rainforest, but marine organisms take the bait. Plankton, seaweed and other photosynthesizers produce over half of the world’s oxygen. We know the answer to this and other fun science facts, but here are other ocean scientists found


4Animals use Earth’s magnetic field for orientation:
Lost land animals may not be able to find their way home, but sea animals might. According to the US geological survey (USGS), “there is evidence that some animals, like sea turtles and salmon, have the ability to sense the Earth’s magnetic field and to use this sense for navigation.”


5 A cloud can weigh over a million pounds:
Your childhood dreams of floating on a weightless cloud may get rained on with this fact: the average cumulus cloud can weigh up to million pounds A million pounds! That’s about as heavy as the world’s largest passenger jet.

6 Soil is alive and well:
In just one teaspoon of soil, there are more microorganisms than people on the planet, said the “Millions of species and billions of organisms—bacteria, algae, microscopic insects, earthworms, beetles, ants, mites, fungi and more—represent the greatest concentration of biomass anywhere on the planet.”


7 Rats laugh when being tickled:
These creatures are more dynamic then we think. Rats have the ability to “laugh” when tickled. A National Geographic video demonstrated that rats respond positively to tickling. And they even chase after the researcher’s hand in a playful manner.


8 There are more trees on Earth than stars in our galaxy:
NASA experts believe there could be anywhere from 100 billion to 400 billion stars in the Milky Way galaxy.


9 Oxygen has a color:
As a gas, oxygen is odorless and colorless. In its liquid and solid forms, however, it looks pale blue. Some science facts are just plain weird.

10 Only two letters don’t appear in the periodic table:
The letters J and Q don’t appear anywhere on the periodic table. Go ahead and double check. We’ll wait.


11 Bananas are radioactive:
For one of our strangest science facts, bananas contain potassium, and since potassium decays, that makes them slightly radioactive. But this is one of those fun science facts you don’t need to worry about. You’d need to eat 10,000,000 bananas at once to die of radiation poisoning.


12 Hot water freezes faster than cold water:
This fact seems counterintuitive, but it’s called the Mpemba effect, after a Tanzanian student named Erasto Mpemba who told his teacher than a hot mixture of ice cream froze faster than a cold one. Scientist believe is because the velocities of water particles have a specific disposition while they’re hot that allows them to freeze more readily. If proven correct, this finding could also have implications in daily life, like cooling down electronic devices.


13 Cold water heats up faster than hot water:
The researchers who investigated the cause of the Mpemba effect made this discovery as well. They unsurprisingly named the phenomenon the inverse Mpemba effect.


14 Humans are related to fungi:
A 2015 study from the University of Cambridge suggests that mankind may have evolved with genes that came from plants.

15 It can rain diamonds on other planets:
Diamonds are definitely the Milky Way galaxy’s best friends. Studies have examined the potential that Neptune, Uranus, Jupiter, and Saturn have to produce diamonds. The atmospheres in all four planets have such extreme pressure that they can crystalize carbon atoms and turn them into diamonds.

16 You can make balls fly:
If you spin a ball when you drop it, it will fly through the air as it falls. This is called the Magnus effect, and it makes playing tennis and soccer a whole lot easier.


17 Water can exist in three states at once:
This is called the Triple Boil, and at that u to achieve, so don’t even think about trying it at home.


18 Only one type of mammal has wings:
Those mammals would be bats. While flying squirrels can jump from trees and glide, they can’t truly fly like bats can.

nice and insightful topic... nice job op
