In-freaking-credible Dolphin!!

As indicated, this is amazing... this dolphin, in some sort of aquarium, is blowing and playing with bubble rings. It can also create a smaller bubble ring while bursting the larger one. I've watched this several times, in slow motion, and play/pause... I think this video is legit.

This really is incredible and the video is totally safe for work.

Ah yes, I don't know if bubble rings have come up on the NWDC before, but there is something awesome about them. On my last dive at the safety stop I was working on them, it is pretty fun, definitely tricky with cold lips after a long dive. I have heard multiple techniques or words to keep in mind while releasing air, but are there any masters here? Care to share your tips? A fun skill to get down.
