And I thought it was cool when my dad did this with his pipe. I can't give a description that will adequately describe what you're about to see. It's amazing. And even more amazing, this is apparently something these dolphins didn't do before. A few of them somehow learned it, then the other dolphins in the tank learned from them. Absolutely positively astounding.
