Dolphins playing bubbles

I love this video of the Dolphins blowing bubble rings in water, really amazing!. Both captive and wild dolphins can blow bubble rings, but in captivity they do that to entertain themselves.They are captured blowing puffs of the air and tilting their heads so that they create perfect circle rings. Playing with bubbles is an important part of dolphin's life. Sometimes the size of the bubble is big enough for the dolphins swim through it. Some dolphins don't know how to blow bubbles, so they learn how to do it watching the others. They also like to ride waves like those generated by boats and jump on the waves.This is a lesson to learn: practice makes perfect!
