Some Facts in this World

Hi! Steemian. How are you today? I hope it's better :)
This time I want to share some facts in this world. Maybe, for some people who exist in this world, not yet know many facts in the world. And that's real, guys!
Whether it's facts about human anatomy or other objects on the planet.
Here are the facts I get from various sources:

Astronauts

The astronauts are forbidden to eat peanut-type foods before going into space. Because it can make them easy to fart. And gas farts are very dangerous for their space suits.
Rain Frog

In 1997, one of the cities in Mexico once had a frog rain. The rare event was evenly distributed throughout the country.
A smart Crocodile

Crocodiles are more ingenious than we have ever thought. They deliberately swallowed gravel and rocks in order to dive into deeper water.
The largest gold source on Earth

Apparently the largest gold source is in the Ocean, there are gold that amounts to 200 times more than ever unearthed in human history.

The last one.

The biggest item post ever sent through the Post Office

In 1916, a young businessman named William H. Coltharp decided to build a new bank in Vernal, Utah.
Of course, Coltharp could not post the finished building by mail. He therefore sent him 'wall by wall'.
How? Coltharp asked for a brick of 80,000 seeds placed in 40 chests, each weighing 22 kilograms shipped from a brick company in Salt Lake through the post office.
Coltharp reasoned, postal delivery is the cheapest way of shipping bricks for building construction materials. Because of this Coltharp act, the United States Post Office prohibits the delivery of postal objects exceeding 90 kilograms.
Those are some facts that I got, strange indeed but it's real!
