Wow, amazing. They're obviously not just bored shitless due to being kept in captivity - you can tell because they're smiling. Must be so much fun for them living in a tank.

Yeah I don't think they could say in more emphatic terms, let me the fuck out of here, you have no right to keep me here you fuckwits, this is like you being kept prisoner by chimpanzees you fucking morons. Unfortunately, the keepers don't really seem to be getting the message. How is a circular bubble even possible?

If you pay attention you'll notice that the bubbles are actually morse code for "I miss my family and all my friends"

i was more confused by the physics of how a circle of air was held underwater - would the force not have to be from the outside to keep it from rising? and from the inside to keep it open?

My take on this is that its all down to angular momentum. Clearly the first problem is that a bubble normally wants to be spherical due to surface tension. In order to combat this the dolphins set the edge of the bubbles spinning very fast both around the circular axis running in the direction of the circumference of the bubble as well as winding around the bubble at 90 degrees to the circumference (dolphins must give incredible head). In order for the bubble to collapse, it would need to shed the (relatively) enormous angular momentum - hence it cant collapse because every time it starts to collapse the conservation of angular momentum causes it to spin faster and the bubble is forced outwards again by "centrifugal force". Very clever! The multitude of axes containing significant angular momentum means that the bubble is essentially an incredibly complex gyroscope and for the same reason, it tends to resist movement in any direction. from the movie it is clear that the gyroscopic effect is stronger than the effect of bouyancy.
