ELI5: Explain Like I'm 5

Vortex ring gun

So imagine you have a straw and some bubbles in your drink. When you blow air through the straw, you can make the bubbles move around and even shoot out of the drink!

Now, imagine a really big straw and instead of bubbles, you have rings of air spinning in circles. This is called a vortex ring. If you shoot these vortex rings from a gun, they can travel really far and knock over things in their path!

But how do you make these vortex rings? Well, you need something called a diaphragm. This is like a tiny drum that vibrates really fast to push air out in bursts. When the bursts of air are timed just right, they create the spinning vortex ring that you can shoot.

So in summary, a vortex ring gun is like a big straw that shoots spinning rings of air. It uses a special drum called a diaphragm to create the rings and can knock things over with its powerful air blasts!
