The dolphins were playing and having fun with their rings, just like humans. Completely impractical.

The computer animation, though, undermined the beauty and frivolity of the real rings.

A more accurate name is a vortex tube. Bubble implies the fluid is stationary (that is, not rotating). They can be created with any high velocity burst in a fluid so the volcano one is legit. I'm sure they happen in nature a lot more often but just aren't visible.

It is impossible for the tube to end within the fluid, as seen when the dolphin splits one in two, and the faster it spins the more stable it is which is probably why the volcano one doesn't oscillate like the dolphin's did.

How appropriate this was posted the day before my exam on fluid mechanics (I'm not kidding, Mech Eng graduate school). We watched the dolphin video in class. My prof was a little too excited about it.

So should the dolphin stuff not be included also? They are intelligent creatures and they made artificial rings.

It's not like we blew up a bomb with the intent of seeing super cool rings of smoke.

The Tsar bomb shouldn't be in this compilation if it's titled 'nature's smoke rings', humans did that and it never would have occurred naturally.

Is there any particular reason there's a drating share button that appears on top of the video controls?
