Everything is in the title, this is the world smallest gun and this is very tiny ! It makes a lot of noise for this size, don't you think ? But if want to kill someone with this gun I hope for you this guy will be the world smallest person too 🙂 The guy in the video shoots a can and the bullet doesn't come of it so this is really not impressive. What's fun is how the bullets are made and how you load this gun.
