YouTube - SeaWorld Dolphin Bubbles
The dolphins at Sea World Florida's Dolphin Cove are teaching eachother a curious activity. They are learning to blow bubbles. More specifically, they are emitting bubble rings from their blow holes, and pushing, spinning and manipulating the rings to make them bigger smaller or bigger. They even know how to keep the bubble rings from floating to the surface. Check out Sea World's Dolphin Bubbles site, and the You Tube link above.
