The man responsible for the creation of arguably the most well-known cartoon character in the world, Mickey Mouse, was afraid of mice! Does it get any more ironic? Walt Disney had a deep-seated fear of the four-legged creatures. But he also saw them as sympathetic. That was why he choose to base Mickey on a mouse. It turned out to be a solid decision from Disney. Mickey Mouse helped turn Disney into one of the world’s biggest entertainment companies. 

Pioneer 10 was the first spacecraft to traverse the Main Asteroid Belt. It took place in 1972. The apparatus disproved the idea that the belt contained dust that could harm the technological components aboard.

It first entered a stable orbit around the asteroid Vesta before moving on to Ceres.

Let us explain why you should have an eye test before you book one. A butterfly's wings are covered in thousands upon thousands of tiny scales. And the hues you see as a butterfly flies through your yard are the reflection of different colors through the scales.

Because they generate sound through lip vibration, instruments like conch shells and shofars (made of hollowed-out animal horns) are still regarded as brass. Since they haven't undergone much modification from their original state and don't have valves or slides to regulate pitch, they are frequently referred to as "natural trumpets." Despite being primarily made of brass, other traditional brass instruments like trumpets and trombones may also contain some copper or other metals.

One of the most well-known facts about Jaigarh Fort is that it is home to the World's Largest Cannon on Wheels. This, known as Jaivana, was made in the Fort's cannon foundry. I don't think my photographs do this cannon's massive size justice. The amusing aspect is that, despite its size, it was never utilized in a conflict! It was only fired once for a test, and the cannon projectile went 35 kilometres.

The most prestigious university of America cannot have its students getting distracted from school now, can they?

More people celebrate Cinco de Mayo in the US than in Mexico. An annual Chihuahua race is held to celebrate in Chandler, Arizona and Denver, Colorado.

They may be taught to use enormous blades connected to their tusks to slowly destroy bones, crush skulls, twist off limbs, or even execute people. This manner of death was still used in various regions of Asia until the late nineteenth century.
