Octupus Frees Itself From Jar [Video]

I'm intrigued by sea creatures. Mostly because a lot of them are really, really cool, but also because some of them are able to do some pretty amazing things.

Case in point - this octopus who manages to free itself from the inside of a sealed jar!

I don't know the circumstances involved - why was the octopus in the jar in the first place? Had he done this trick before? Was this some sort of science experiment?

All I know is that this is one super smart octopus, and the whole time I was watching the video I just kept thinking "You can do it!"
