Mt. Etna Blowing Smoke Rings

While perfectly explainable, it's still pretty cool.

I remember seeing people who could blow smoke rings. Don't see too much of that anymore. And for that I am glad.

There’s actually contests for this… put on by vaping… I understand it’s going to be in the next Olympics…

I also remember my parents blowing smoke rings to entertain us kids.

Here's something even cooler: Dolphins blowing bubble rings and playing with them.

From which end?

Usually from the intake. In my very distant past, I do recall flames exiting from the exhaust however. Seemed to coincide with mass consumption.

If you could eat a can of beans,and blow rings underwater that would be a real a talent! If you covered the beans with lots of hot sauce,you might even blow rings of fire(apologies to J Cash).

Along with Rixter's post above, it is a remarkable display of intelligence that these animals engage in an activity that (I think) would have nothing to do with their survival or procreation. But then again, maybe it does impress the other sex?
