Update: John Rennie, over at the Gleaming Retort, has a post that discusses dolphin bubble blowing in more detail.
Apologies, dear readers–there will be no Small Wonders this week. I don’t even have a good excuse. It’s just been a crazy few days and the week somehow got away from me.
But let me make it up to you with this awesome dolphin video. It shows dolphins blowing rings of bubbles underwater. Rather than letting the bubbles rise to the surface, the cetaceans somehow manage not only to keep them submerged but also to play with the rings.
