Best Facts of All Time

1)Jellyfish evaporate in the sun. They're 98% water!
When jellyfish are in the water, they can be a bit intimidating. Their tentacles can pack a painful electrical shock. However, once they wash up on shore, they are anything but intimidating.
It turns out that jellyfish are 98% water. Most are transparent and bell-shaped. If they end up on the beach, they will most likely evaporate in a few hours and mostly disappear.
Jellyfish also don’t have brains, bones or a heart. They do have rudimentary sensory nerves though.

2)When you laugh while being tickled, what you are experiencing is actually a form of panic.
If you’re ticklish, you know the automatic laugh response that occurs when you are tickled. This can range from giggling to uncontrollable shrieks of laughter. However, your body is actually responding with panic and anxiety.
This is actually the body’s defense mechanism. It is believed that the response is meant to protect you from dangerous things on your skin, such as poisonous insects. The body needs to react quickly to this unanticipated touch and does so with a panic response

 3)Those stars and colours you see when you rub your eyes are called phosphenes.
Have you ever closed your eyes, rubbed them and seen stars? Or at least little pops of light? It turns out that those pops of light have a name: phosphenes.
They are a phenomenon characterized by seeing light without light actually entering the eye. This rubbing mechanically stimulates the cells of the retina causing this effect. Sometimes, these phosphenes can still be seen for moments after you open your eyes.
Meditators have also reported experiencing phosphenes, and they have actually been known since antiquity. Ancient Greeks described them. Other reasons people ‘see stars’ are because of sneezing, coughing, blowing your nose or receiving a blow to the head.

4)Grapes EXPLODE when you put them in the microwave!
You may have heard of frozen grapes as a tasty snack, but what about heating grapes in the microwave? You probably shouldn't try this one. It turns out that grapes react very oddly when they're microwaved.
Since grapes are full of moisture, when they are microwaved, that moisture turns to steam. If the stem is still attached to the grape and there is nowhere for the steam to escape, it will explode slightly and rupture the skin.
If you place two grapes close together with their stem holes facing each other, some arcing and sparking will occur. If there is just a single grape with its stem hole open, it will let out a stream of steam. Good thing we don't serve grapes warm.

5)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 an overcrowded 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.
The square boxes they're grown in are the exact dimensions of Japanese refrigerators, which means they fit perfectly. At $82 each, these square watermelons probably wouldn't be too popular in the United States. Our solution for a lack of refrigerator space? Smaller, seedless watermelons.

6)An elephant can die from a broken heart.
It turns out that elephants are highly emotional animals. They form close-knit relationships with one another and mourn the loss of loved ones. At times, if a fellow elephant dies, the others in the herd will gather around and pay their respects as if at a funeral.
If a baby elephant loses its mother, it will grieve. The elephant will often become withdrawn and emaciated. Other members of the herd will gather around and nurse the orphan back to life. Elephants can form deep attachments with humans too.
In one case, an elephant handler raised a baby elephant. She had to go away for a brief time to attend her daughter’s wedding. When she returned, she found that the baby elephant had died of a broken heart at her absence.

7)It cost 7 million dollars to build the Titanic and 200 million to make a film about it.
The film “Titanic” was incredibly successful. It won 11 Academy Awards and launched the careers of its leads, Kate Winslet and Leonardo DiCaprio. In order to make such an epic film, the producers had to spend a lot of money.
Specifically, it cost $200 million. Part of the cost of the film was building a partial replica of the ship itself. The movie actually cost more than the real Titanic.
In 1910-1912 when the Titanic was being built, it cost about $7.5 million. In 1997 dollars, when the movie was made, that would be about $120-$150 million.

8)Most people are unable to laugh on command.
Laughter is an interesting thing—it’s part of a universal human language that all people understand. It’s such a natural response that we often don’t even realize we’re doing it. People have many different types of chuckles and many different reasons for their laughter.
One thing is common though—most people cannot laugh on command. If they do laugh, it is forced and often inauthentic. It will take a few minutes to come up with an actual laugh. This suggests that we can’t deliberately activate the brain’s mechanisms for affective expression.
