## The total weight of all the ants on Earth is about the same as the weight of all the humans on earth.

Unless you leave food out and attract them, humans rarely have a need to think about ants. They're tiny, not poisonous and not particularly terrifying, like say, spiders. However, they far outnumber humans on earth--by one million to one!

Funnily enough, they are also roughly a millionth of a human in size too. Do the math--the total weight of all the ants on earth matches the total weight of the entire human population.

There are 10,000 different types of ants and they've been around for a long time. Ancients ants have been discovered in fossilized sap from 100 million years ago!

Over time, ants have changed very little. Their way of life and survival is successful. Some scientists attribute this to their unselfish ways. Ants live in colonies and bring their prey back to their many relatives to share.

## 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.

## A Rubik's cube has 43,252,003,274,489,856,000 possible configurations.

With 6 colored sides, 21 pieces and 54 outer surfaces, there's a combined total of over 43quintilliondifferent possible configurations. To put that into perspective: if you turned the Rubik's cube once every second it would take you1400 trillion yearsto finish to go through all the configurations.If you had started this project during the Big Bang, you still wouldn't be done yet.

Another way to think about this is, if a person had as many Rubik's cubes as there were possible configurations, they could cover the surface of the Earth 275 times. And if one considers the number of configurations you could reach by disassembling and reassembling the cube, the number would be nearly 12 times that many.(source)

## 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.

## 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.
