gun

Guns have been around for more than 1,000 years, affecting war and society at large in a way that perhaps no other invention can compare.

Ammunition ammunition everyone knows but the way they operate is still a mystery to many people.

With a size no bigger than a nail, the world's smallest gun can be worn on the finger like a jewelry.

The bullet flew so fast that you needed to slow that moment thousands of times to see how it flew out of the barrel.

Until now, guns are often associated with scary, but a camcorder in the shape of a gun is an interesting idea.
